Mouse::XS(3)	      User Contributed Perl Documentation	  Mouse::XS(3)

NAME
       Mouse::XS - A Mouse guts	in XS

VERSION
       This document describes Mouse version 2.0.0

DESCRIPTION
       Mouse has an optional XS	implementation,	which is automatically built
       and used	if available. According	to benchmarks, this is about 2 times
       faster than Mouse::PurePerl.

   INSTALL
       The XS implementation are selected by default, but you can force	it by
       passing the "--xs" option to Makefile.PL.

	   perl	Makefile.PL --xs

       If you do not want to build the XS implementation, you can pass the
       "--pp" option to	Makefile.PL.

	   perl	Makefile.PL --pp

       Or if you use "cpanm" (>= 1.7), you can give "--pp" option to "cpanm".

	   cpanm --pp Mouse

   The MOUSE_PUREPERL (or PERL_ONLY) environment variable
       It can be used to enable	the use	of Mouse::PurePerl in order to test
       and debug programs that use Mouse.

CAVEAT
       There are some Mouse::XS	specific features.

       Mutating	references to the return values	of getters
	   When	you take a reference from Mouse	getters, like "$ref =
	   \$obj->foo",	the $ref refers	"\$obj->{foo}".	That is, mutating
	   $$ref also alters "$obj->{foo}". The	behavior may confuse you so
	   you'd better	avoid to take a	reference directly from	getters.

	   See <https://rt.cpan.org/Ticket/Display.html?id=82945> for details.

DEPENDENCIES
       The XS implementation requires Perl 5.8.1 or later, and a C compiler.
