=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>.
