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 , 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.
