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.
