NAME
       Moose::Cookbook::Basics::Immutable - Making Moose fast by making your class immutable

VERSION
       version 2.1202

SYNOPSIS
	 package Point;
	 use Moose;

	 has 'x' => ( isa => 'Int', is => 'ro' );
	 has 'y' => ( isa => 'Int', is => 'rw' );

	 __PACKAGE__->meta->make_immutable;

DESCRIPTION
       The Moose metaclass API provides a "make_immutable()" method. Calling this method does two things to your class. First, it makes it faster.
       In particular, object construction and destruction are effectively "inlined" in your class, and no longer invoke the meta API.

       Second, you can no longer make changes via the metaclass API, such as adding attributes. In practice, this won't be a problem, as you
       rarely need to do this after first loading the class.

CONCLUSION
       We strongly recommend you make your classes immutable. It makes your code much faster, with a small compile-time cost. This will be
       especially noticeable when creating many objects.
