NAME ^

Fun - simple function signatures

VERSION ^

version 0.05

SYNOPSIS ^

  use Fun;

  fun float_eq ($a, $b, $e = 0.0001) {
      return abs($a - $b) < $e;
  }

DESCRIPTION ^

This module provides fun, a new keyword which defines functions the same way that sub does, except allowing for function signatures. These signatures support defaults and slurpy arguments, but no other advanced features. The behavior should be equivalent to taking the signature, stripping out the defaults, and injecting my <sig> = @_ at the start of the function, and then applying defaults as appropriate, except that the arguments are made readonly.

EXPORTS ^

fun

Behaves identically to sub, except that it does not support prototypes or attributes, but it does support a simple function signature. This signature consists of a comma separated list of variables, each variable optionally followed by = and an expression to use for a default. For instance:

  fun foo ($x, $y = 5) {
      ...
  }

Defaults are evaluated every time the function is called, so global variable access and things of that sort should work correctly.

fun supports creating both named and anonymous functions, just as sub does.

BUGS ^

No known bugs.

Please report any bugs through RT: email bug-fun at rt.cpan.org, or browse to http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Fun.
