1521	Continuations interact badly with .return	arnsholt		"I'm trying to implement non-deterministic search (backtracking), for a tentative continuation-passing Prolog on Parrot. Fiddling with this, I've stumbled upon what seems like a strange issue with continuations.

The code is adapted from the Scheme in Paul Graham's On Lisp.

test.pir contains my original test code. As is clear from the output, choose() gets the right value, but the calling code somehow always gets the first value.

In an attempt to condense the code a bit I wrote bug.pir, which exhibits some interesting behaviour. The return value keeps the value from the last return. Possibly the continuation resumes from a slightly wrong position?"	bug	closed	normal		none	trunk	medium	fixed					darwin
