NAME

       Sub::Name - (re)name a sub

SYNOPSIS

	   use Sub::Name;

	   subname $name, $subref;

	   $subref = subname foo => sub { ... };

DESCRIPTION

       This module has only one function, which is also exported by default:

   subname NAME, CODEREF
       Assigns a new name to referenced sub.  If package specification is omitted in the name, then the current package is used.  The return value
       is the sub.

       The name is only used for informative routines (caller, Carp, etc).  You won't be able to actually invoke the sub by the given name.  To
       allow that, you need to do glob-assignment yourself.

       Note that for anonymous closures (subs that reference lexicals declared outside the sub itself) you can name each instance of the closure
       differently, which can be very useful for debugging.

NAME

       Object::Role - base class for non-Moose roles

SYNOPSIS

	{
	  package Object::Dumpable;
	  use base qw/Object::Role/;
	  use Data::Dumper;
	  sub import
	  {
	    my ($class, @args) = @_;
	    my ($caller, %args) = __PACKAGE__->parse_arguments(undef, @args);
	    my $coderef = sub
	      {
		my ($self) = @_;
		return Dumper($self);
	      };
	    __PACKAGE__->install_method(dump => $coderef, $caller);
	  }
	}

	{
	  package Foo;
	  use Object::Dumpable;
	  sub new { ... }
	}

	{
	  package main;
	  my $foo = Foo->new;
	  warn $foo->dump;
	}

DESCRIPTION

       This will be better documented once I fully understand it myself!

       The idea of this is to be a base class for roles like Object::DOES, Object::Stash and Object::ID. It handles parsing of import arguments,
       installing methods into the caller's namespace (like Exporter, but using a technique that is immune to namespace::autoclean) and tracking
       which packages have consumed your role.

       While "Object::Role" is a base class for roles, it is not itself a role, so does not export anything. Instead, your role must inherit from
       it.

   Methods
       "parse_arguments($default_arg_name, @arguments)"
	   Will parse:

	     package My::Class;
	     use My::Role -foo => 1, -bar => [2,3], 4, 5;

	   as:

	     (
	       'My::Class',   # caller,
	       (
		 '-foo' 	    => [1],
		 '-bar' 	    => [2, 3],
		 $default_arg_name  => [4, 5],
	       )
	     )

       "install_method($subname => $coderef, $package)"
	   Installs $coderef as "$package::$subname".

	   Automatically calls register_consumer($package).

       "register_consumer($package)"
	   Records that $package has consumed (used) your role.

       "has_consumer($package)"
	   Check if $package has consumed (used) your role.
