One of the big problems with Parrot's n_* opcodes is that they
often assume that the type of the result should be the same as
the type of the first operand . . .
I kinda thought it wouldn't be that easy. Sigh.
All of the mechanisms I've been able to find in Parrot for
converting an arbitrary PMC to a number seem to result in
the code for infix:<*> that we have now. I'm open for
suggestions to improve this, though.

Hmm. My instinct would be to rely on MMD:
.sub 'infix:*' :multi(Perl6Array,_)
.param pmc a
.param pmc b
$P0 = new 'Integer'
$P0 = a
.return 'infix:*'($P0, b)
.end
.sub 'infix:*' :multi(_,Perl6Array)
.param pmc a
.param pmc b
$P0 = new 'Integer'
$P0 = b
.return 'infix:*'(a, $P0)
.end
This exposes an MMD bug (it runs forever), but something like this
should work once it's fixed.
