NAME

Sub::Alias - Simple subroutine alias.

VERSION

This document describes Sub::Alias version 0.01

SYNOPSIS

    use Sub::Alias;

    sub name { "David" }
    alias get_name => 'name';

    print get_name; # "David"

DESCRIPTION

This module does a compile-time code injection to let you define subroute aliases by names or code refs.

INTERFACE

By <use Sub::Alias>, an new keyword 'alias' is introduced in the scope. Let's say there is an existing subroutine named "wine" and we want to create an alias to it named "vino".

The following 2 ways should be trivial to understand:

    # By name
    alias vino => "wine";

    # By code reference
    alias vino => \&wine;

The first argument can be a scalar variable containing the new name:

    my $n = "vino";
    alias $n => \&wine;

Complex exressions that computes a new name is not supported.

DEPENDENCIES

Keyword::Declare

INCOMPATIBILITIES

Perl versions older than 5.12 are not supported.
