NAME

like - Declare support for an interface

VERSION

This document describes like version 0.02

SYNOPSIS

  package MyThing;

  use like qw( some::interface );

  # later

  if ( MyThing->isa( 'some::interface' ) ) {
    print "Yes it is!\n";
  }
  

DESCRIPTION

Allows a package to declare that it ISA named interface without that interface having to pre-exist.

This

  package MyThing;

  use like qw( some::interface );

is equivalent to

  package some::interface; # make the package exist

  package MyThing;

  use vars qw( @ISA );
  push @ISA, 'some::interface';

The like declaration is intended to declare that your package conforms to some interface without needing to have the consumer of that interface installed.

There is no test that your package really does conform to any interface (see Moose); you're just declaring your intent.

CONFIGURATION AND ENVIRONMENT

like requires no configuration files or environment variables.

DEPENDENCIES

None.

INCOMPATIBILITIES

None reported.
