While playing with calling threaded subs, I came along a thing which I think might be suboptimal:
pdd03 states that the method PMC should go into P2. This doesn't really play with Perl5 <-> Perl6 interoperbility IMHO. Perl5 methods are plain subs, where the first param is the object.
PDD 03 states that the *object* goes in P2. This works out just fine with perl 5 style method calls, where the argument list doesn't distinguish the object other than by position. What happens is that when a perl 5 sub is called, @_ is a combination of P2 if it's non-NULL, and the remaining PMC registers. It's slightly more work for the perl 5 code generator to handle the check, but other than that it shouldn't be a problem.
