Raimond Dragomir <raimond.dragomir@gmail.com> writes: > Who said the parent's locals should be captured? Local variables are > "local" variables. When parent exits, its locals are gone. Simple as that. The problem is that the quotation is potentially still around, holding references to those locals. In Lisp this is called the upward funarg problem and it's handled by putting the parent locals in the heap, so they get gc'd after the quotation (called a closure in Lisp terminology) becomes unreachable. In C++11, calling the closure after the parent returns is UB. Maybe that's reasonable for Forth as well.
