SMOP p6opaque Implementation: Revision 25
The p6opaque Responder Interface is the default responder for all Perl 6 objects, according to the [SMOP OO API].
^ p6opaque Structure
I use 'repr' as class keyword here to indicate that this is not a real class, but the low-level reponder interface that intercepts the calls with the '^!' prefix. Everything else should be delegated to the metaclass instance.
> repr p6opaque {
>> has $.^!instanceof; # direct delegation of a single prototype, used by most object instances.
>> has $.^!WHENCE; # autovivication closure, used by autovivification
>> has p6opaque_proto %.^!proto_storage handles *;
>> has Hash of Hash %.^!instance_storage;
>> default ($ri, $identifier, $capture) {
>>> $capture.invocant.^!how.dispatch($ri, $identifier, $capture);
>> }
> }
> repr p6opaque_proto {
