=head1 NAME

Cache::Ref::Null - Caches nothing

=head1 SYNOPSIS

    # useful for comparing the effect of a cache compared to no
    # caching without code changes:

    my $c = Cache::Profile::Compare->new(
        caches => [
            Cache::Ref::Foo->new( ... ),
            Cache::Ref->Null->new,
        ],
    );

=head1 DESCRIPTION

This cache implementation will cache nothing.

This is primarily intended for testing or comparing runtime
without a cache against runtime with a cache.

It's like L<Cache::Null> but supports the additional methods in
L<Cache::Ref>.
