I was trying to figure out exactly how Captures manage to stay invisible even though functions return them, yet still let you use Capture objects when you want to. Please see my conclusions at <http://www.dlugosz.com/Perl6/web/return.html>. The Summary at the very bottom clarifies the Synopses.
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? Regards, TSa. -- "The unavoidable price of reliability is simplicity" -- C.A.R.
