The current method of just load'ing .scm files was just so I could get
something going.  I actually want to make mod_guile flexible enough to
do just about anything.  The current mg_scm_handler needs to be written
in scheme and a good way of abstracting it so other kinds of handlers
could be written easily.

I see a whole spectrum of scheme-enabled web pages.  There is the basic
html with a little bit of scheme thrown in here or there, possibly
written using a gui web development tool. There is just raw scheme that
uses display to generate html. How about something like a scheme based
markup language? Like laml or some of the stuff that address@hidden has
done.  I'd like to see handlers for all of these, or rather, I'd like
the hooks to be there so that these (and any other) handlers are easy to
write.

At any rate, I was planning to at least have some kind of caching of
.scm files to speed things up. The .scm file would only be re-read if it
changed.  I also don't like the idea of passing the request rec in the
Request global variable. Ugh!  But .sch files don't really have
arguments.  There are lot's of questions on how to go about doing these
things, and I was getting stuck.  I was hoping wiser and more
experienced people could offer suggestions and insight. ;^)

Yes.  Have you ever looked as quixote?  It's in Python, not Scheme, but
there are some ideas in there that are ver interesting.  Like the way
the module namespace and the url name space sort of blend together.

Thanks.
