True; I've used stack-catch in my latest suggestion.

I agree w.r.t. documentation but am not convinced about C. I'm
beginning to think that Guile should actively encourage people to do
as much as possible in Scheme, and I see no reasons (yet) why this
kind of error handling has to be done in C.

Thanks - I'll take a look.
