VERSION

This document describes Scalar::Alias version 0.06.

SYNOPSIS

        use Scalar::Alias;

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

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

        # %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.
