A PMC, which presumably performs the Integer role (in Parrot terms). If Tcl on Parrot doesn't return this, Tcl on Parrot is wrong and bad. This is why we have PMCs and PMC roles (okay, why we will have PMC roles) and especially why we have vtables. If Tcl decides to reimplement its own data structures and not use vtables and PMC roles in the same way as other languages, it will interoperate about as well as the prototypical ugly American tourist complaining about Parisian traffic on Bastille Day. I have trouble imagining that any other approach to interoperability works any better (and devolves into lesser utter chaos -- maybe I can get a hotel named after me for proving the existence of infinite forms of utter chaos). The fact that tie() works in Perl 5 suggests that this approach works in practice. Where's the problem? -- c
