The user can enter scheme funtions in the middle of running either by
typing into an entry box or by loading a file.  What I want is a way
to keep track of any functions which are defined in this manner so
that they can be written out for re-loading next time the program is
run.  

Hmm, now that I think of it maybe it is as simple as just manually
saving all strings entered.  But, I was wondering if there was a way
of putting all user entered functions into some kind of namespace or
environment and then telling guile to dump the contents of ths space
to a file.

Thank you, I will look into using these.
