Comment (by jpet):

 The linked-to proposals and discussion are mostly about generating what
 the stack "would be" if evaluation order had been strict.

 I'm suggesting what the previous comment does, something much simpler (and
 IMHO much more useful)--I want to see a dump of the actual stack that
 actually exists in memory. Walking these stacks is easy, well-defined, and
 portable; the only obvious obstacle seems to be annotating code with
 source line and file info.
