I like the concept of auto-collapsing ReturnCaptures. It reminds me
to my idea of an AssignmentProxy as discussed in "assignable mutators
(S06/Lvalue subroutines)". If such a ReturnCapture could also be
preliminary of some kind, then lvalue subs could be lazily resumed when
the rvalue comes in. Also infix:</> needs a lazy item that is collapsed
into Int, Num or Rat depending on the constraint of the container it
ends up in eventually. An Any gets the Rat. Hmm, and a Str perhaps the
two constituting Ints as fraction put into lowest terms?
