pdd03 and method calls

[Leopold Toetsch]

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. I dunno, if Ponie will ever 
use ParrotClass/ParrotObject, but I'm sure, that calling Perl6 methods 
should work (and vv). So me thinks that the method PMC should be the 
first PMC argument living in P5.

sub meth {
  my ($self, $arg1) = @_;
  #    P5    P6
  ...
