NAME ^

Scalar::Alias - Perl extention to declare lexical scalar aliases

VERSION ^

This document describes Scalar::Alias version 0.06.

SYNOPSIS ^

        use Scalar::Alias;

        sub inc{
                my alias $x = shift;
                $x++;
                return;
        }

        my $i = 0;
        inc($i);
        print $i, "\n"; # => 1

        my %h;
        my alias $foo = $h{foo};

        # %h is empty

        $foo = 10;

        # %h is {foo => 10}

DESCRIPTION ^

Scalar::Alias allows you to declare lexical scalar aliases.

There are many modules that provides variable aliases, but this module is faster than any other alias modules, because it walks into compiled syntax trees and inserts custom opcodes into the syntax tree in order to alias variables.

DEPENDENCIES ^

Perl 5.8.1 or later, and a C compiler.

BUGS ^

No bugs have been reported.

Please report any bugs or feature requests to the author.
