What Is The Meaning Of The Name Trevrizent?


Roles are added to a class or object with the does keyword, as opposed to inheritance's is. Among these were that Perl's regexes were "too compact and 'cute'", had "too much reliance on too few metacharacters", "little support for named captures", "little support for grammars", and "poor integration with 'real' language".

See Aktuelle Rechtslage in Deutschland , last paragraph. A blessed object can have methods invoked on it using the "arrow syntax" which will cause Perl to locate or "dispatch" an appropriate subroutine by name, and call it with the blessed variable as its first argument.

While extremely powerful, it makes the most common case of object orientation, a struct -like object with some associated code, unnecessarily difficult. In addition, because Perl can make no assumptions about the object model in use, method invocation cannot be optimized very well. In the spirit of making the "easy things easy and hard things possible", Perl 6 retains the blessing model and supplies a more robust object model for the common cases.

The dot replaces the arrow in a nod to the many other languages e. Java , Python , etc. Some languages call these fields or members. The method used to access an attribute is called an "accessor". Auto-accessors are methods that are created automatically, as the method x is in the example above.

These accessor functions return the value of the attribute. Auto-accessors can be replaced by user-defined methods, should the programmer desire a richer interface to an attribute. Attributes can only be accessed directly from within a class definition. All other access must go through the accessor methods. Roles in Perl 6 take on the function of interfaces in Java , mixins in Ruby, and traits [38] in the Smalltalk variant Squeak. These are much like classes, but they provide a safer composition mechanism.

Roles define nominal types; they provide semantic names for collections of behavior and state. The fundamental difference between a role and a class is that classes are instantiable; roles are not. Essentially, a role is a bundle of possibly abstract methods and attributes that can be added to a class without using inheritance. For example, a Dog is a Mammal. Dogs inherit certain characteristics from Mammals, such as mammary glands and through Mammal's parent, Vertebrate a backbone.

Dogs may have one of several distinct types of behavior; for example, a Dog may be a Pet , a Stray , or a Guide for the blind. However, these are simply sets of additional behaviors that can be added to a Dog; a Cat can equally be a Pet or Stray, for example. Roles are added to a class or object with the does keyword, as opposed to inheritance's is. The keywords reflect the differing meanings of the two features: Although roles are distinct from classes, both are types, so a role can appear in a variable declaration where one would normally put a class.

Perl's regular expression and string-processing support has always been one of its defining features. Perl 6 provides a superset of Perl 5 features with respect to regexes, folding them into a larger framework called " rules " which provide the capabilities of context-sensitive parsing formalisms such as the syntactic predicates of parsing expression grammars and ANTLR , as well as acting as a closure with respect to their lexical scope.

Anonymous rules can also be introduced with the regex or rx keyword, or they can simply be used inline as regexps were in Perl 5 via the m matching or s substitute operators.

In Apocalypse 5 , Larry Wall enumerated 20 problems with "current regex culture". Among these were that Perl's regexes were "too compact and 'cute'", had "too much reliance on too few metacharacters", "little support for named captures", "little support for grammars", and "poor integration with 'real' language". Some Perl 5 constructs have been changed in Perl 6, optimized for different syntactic cues for the most common cases. For example, the parentheses round brackets required in control flow constructs in Perl 5 are now optional: Also, the , comma operator is now a list constructor, so enclosing parentheses are no longer required around lists.

Perl 6 allows comparisons to "chain". That is, a sequence of comparisons such as the following are allowed:. This is treated as if each left-to-right comparison were performed on its own, and the result is logically combined via the and operation. Perl 6 uses the technique of lazy evaluation of lists that has been a feature of some functional programming languages such as Haskell: The code above will not crash by attempting to assign a list of infinite size to the array integers , nor will it hang indefinitely in attempting to expand the list if a limited number of slots are searched.

Related to lazy evaluation is the construction of lazy lists using gather and take , behaving somewhat like generators in languages like Icon or Python. Perl 6 introduces the concept of junctions: These values can be used in any code that would use a normal value.

Operations performed on a junction act on all members of the junction equally, and combine according to the junctive operator. In comparisons, junctions return a single true or false result for the comparison. Junctions can also be used to more richly augment the type system by introducing a style of generic programming that is constrained to junctions of types:.

In low-level languages, the concept of macros has become synonymous with textual substitution of source-code due to the widespread use of the C preprocessor. However, high-level languages such as Lisp pre-dated C in their use of macros that were far more powerful. A Perl 6 macro definition will look like a subroutine or method definition, and it can operate on unparsed strings, an AST representing pre-parsed code, or a combination of the two.

A macro definition would look like this: In this particular example, the macro is no more complex than a C-style textual substitution, but because parsing of the macro parameter occurs before the macro operates on the calling code, diagnostic messages would be far more informative.

However, because the body of a macro is executed at compile time each time it is used, many techniques of optimization can be employed. It is even possible to entirely eliminate complex computations from resulting programs by performing the work at compile-time. In Perl 6, the alphanumerics can include most Unicode characters. In addition, hyphens and apostrophes can be used with certain restrictions, such as not being followed by a digit.
