-(define (stack-catch key thunk handler)
- "Like @code{catch}, invoke @var{thunk} in the dynamic context of
-@var{handler} for exceptions matching @var{key}, but also save the
-current stack state in the @var{the-last-stack} fluid, for the purpose
-of debugging or re-throwing of an error. If thunk throws to the
-symbol @var{key}, then @var{handler} is invoked this way:\n
-@example
-(handler key args ...)
-@end example\n
-@var{key} is a symbol or #t.\n
-@var{thunk} takes no arguments. If @var{thunk} returns normally, that
-is the return value of @code{catch}.\n
-Handler is invoked outside the scope of its own @code{catch}. If
-@var{handler} again throws to the same key, a new handler from further
-up the call chain is invoked.\n
-If the key is @code{#t}, then a throw to @emph{any} symbol will match
-this call to @code{catch}."
