A subclass of a PMC delegates to that PMC (via deleg_pmc.pmc). The PMC is the first attribute of that class named '__value'. Your code would look like: .local pmc capt capt = getattribute SELF, '__value' capt[key] = value But this is all clumsy, and might/should change. Therefore I've ci'ed in r15111 another workaround in parrotobject.pmc, which checks, if the parent isa PMC and in that case calls the deleg_pmc method instead of the default. leo
