=head1 NAME
Catalyst::Plugin::Cache::Curried - Curried versions of C<cache_set>,
C<cache_get> and C<cache_remove> that look more like a backend.
=head1 SYNOPSIS
my $curried = $c->cache( %meta );
$curried->get( $key, $value ); # no need to specify %meta
=head1 DESCRIPTION
See L<Catalyst::Plugin::Cache/META DATA> for details.
=head1 METHODS
=over 4
=item new %meta
Create a new curried cache, that captures C<%meta>.
=item backend %additional_meta
This calls C<choose_cache_backend> on the $c object with the captured meta and
the additional meta.
=item set $key, $value, %additional_meta
=item get $key, %additional_meta
=item remove $key, %additional_meta
=item compute $key, $code, %additional_meta
Dellegate to the C<c> object's C<cache_set>, C<cache_get>, C<cache_remove>
or C<cache_compute> with the arguments, then the captured meta from C<meta>,
and then the additional meta.
=item meta
Returns the array ref that captured %meta from C<new>.
=item c
The captured $c object to delegate to.
