Sub::Alias - Simple subroutine alias.
This document describes Sub::Alias version 0.01
use Sub::Alias; sub name { "David" } alias get_name => 'name'; print get_name; # "David"
This module does a compile-time code injection to let you define subroute aliases by names or code refs.
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.
Keyword::Declare
Perl versions older than 5.12 are not supported.
