Re: Questions with embedding guile

["Peter C. Norton" <peter@newcentury.net>]

I can't directly answer your question, but i can offer you a solution that
can help you find your problem.

An approach that another member of this list has turned me on to (thanks,
russ!) is to have your program read from stdin.  Run it as an inferior
process from within emacs (or just a shell or something).  Then you can
put in the expression that you want, get the error that you get, run your
debugger alongside it, etc., and "see" what's going on, interactively
without having to re-compile to insert tests and try new things.
