SMOP p6opaque Implementation: Revision 19
The p6opaque Responder Interface is the default responder for all Perl 6 objects, according to the SMOP OO API.
Several low-level implementations will be needed in order to deploy p6opaque features, all this implementations will represent a "community" of responder interfaces that know the p6opaque structure. The additional responder interfaces are not public, and can only be accessed from the p6opaque implementation.
Below follows the list of low-level responder interfaces in the p6opaque "community".
