The pdds are somewhat unclear, what these vtables should precisely do.
e.g.:
INTVAL does(INTERP, PMC* self, STRING* method)
Determine whether the PMC implements the interface"Interface" is not in the glossary in pdd015 nor specified elsewhere.
I would like to have some vtables to do:
- isa("array") # any kind of array (or is this "does"?)
- can("get_string") # this class or one of the parents but not a dummy in default implements "get_string". (or is this "does"?)
TIA leo
