OK, thanks!  I'll try it out.

If I may make a suggestion - I'd like to see folds on lists and maybe
tuples, too.  Especially in file:consult/1 format files.  Often when
you're coding in a 'data driven' style, lists can get kind of hairy,
spanning multiple lines and so forth...

Um... also, is there a way to, say, fold all funs, but just the funs? 
That would be handy (sometimes I've got one function with a dozen funs
inside it (being the easiest way to use bound variables from the main
function) and they really clutter the main logic.)

OK, thanks again - thanks to yvan as well for pointing this out.

Yeah, I didn't notice the "Edit [Local/User/Global] Options..." menu
item; this approach makes more sense now.

It's not actually that bad - I was exaggerating.  It is rather
heavyweight, though (Motif-based.)  I'd like to be able to jettison
OpenMotif if I can... almost everything else I use regularly (sylpheed,
dillo, gimp, &c) is GTK-based.

It's not as much a matter of 'want' as 'have to', sometimes :)
