=head1 NAME

MooseX::Declare::Syntax::Keyword::Namespace - Declare outer namespace

=head1 SYNOPSIS

  use MooseX::Declare;

  namespace Foo::Bar;

  class ::Baz extends ::Qux with ::Fnording {
      ...
  }

=head1 DESCRIPTION

The C<namespace> keyword allows you to declare an outer namespace under
which other namespaced constructs can be nested. The L</SYNOPSIS> is
effectively the same as

  use MooseX::Declare;

  class Foo::Bar::Baz extends Foo::Bar::Qux with Foo::Bar::Fnording {
      ...
  }

=head1 METHODS

=head2 parse

  Object->parse(Object $context)

Will skip the declarator, parse the namespace and push the namespace
in the file package stack.
