Under Parrot 0.2.3 the following PIR program prints "4" as

   a = 2
   b = a.__add(a)
   print b
   print "\n"
   end
.end

Under Parrot 0.3.0 the same code fails like this:

parrot: src/nci.c:72: get_nci_P: Assertion `n < st->src.n' failed.

Yep. The equivalent tests in t/pmc/mmd.t are still skipped. The problem 
is that the infix multi subs take an optional 3rd argument (the 
destination) and that there is no good means yet to denote :optional 
NCI arguments.

But please note that there is hardly a real need to invoke the method 
directly. Just use:

  b = a + a

This will call the "__add" multi, whatever it is.
