Hmm, Warnocked? I'll assume this is sane, until told otherwise, then. :)

Dewarnocking time.
Are these two assumed to be identical?
multi sub foo ($x, $y)
multi sub foo ($x, $y : )

Darn. I was hoping that Larry would field this one. In his absence, I'll take
a swing at it. The usual all(any(@Larry), none($Larry)) caveats apply.
So I'm finally starting to implement

Hmm, I'm doubting that reflecting how many invocants you have on the
caller side is a good idea. It seems awfully brittle in the face of
reimplementation.
Yep. And that's precisely why we previously ruled against colons in the call

Err, wait. From S06:

handle_event $w, $e: $m;
Is this single-dispatch?
No. I think it's vestigial (or ought to be). Luke's argument against colons in
multimethod calls is compelling from a maintainability point-of-view.

In that case:
$w.handle_event($e: $m);
should be illegal as well, right?
Right.
That is, the App (functional application) form always zero or one
invocants, and it is illegal to specify more than one.
Right.
