Oh, yes, of course. Um, wait. Nope, I still don't follow. The
expression above curries to:
sub { $_[0] < 2 + $_[1] * atan2($pi, $_[2]) or die $_[3] }
But the expression
__ < 2 + __ * sin(__ / 2) or die __
curries to
sub { $_[0] < 2 + $_[1] * sin(sub { $_[0] / 2 }) or die $_[2] }
That's very odd.
I really hope I'm missing something, but __ the way you use it
is too magical. It's not DWIM but DWISHMIIKWIWD (do what I should
have meant if I knew what I was doing).
Your original statement that an ad hoc curried expression stops
at a simple assignment sounds fine to me. (It actually fits in
very well with functional programming which avoids assignment.)
If that rule is modified by an explicit subroutine prototype that
establishes a curry context then I think we can make this stuff
work.
