I think something like this should be shipped in the (system repl
debug) module.  I'm used to quick and easy access to a debugger in
other languages, such as Ruby, and having to wrap your head around the
REPL, debug, and stack code is too much to ask of any new Guiler.

Would a patch like this appeal to the maintainers?
