Sorry for answering late.  However, I don't have good examples for you,
but I suggest to look for uses of scm_internal_catch within guile itself.
For example, in environments.c there is some code using it, also in
numbers.c and some other places.

If you still have difficulties to understand it, tell me and I will go and
try to write something up - it is some time ago since I used that
function.  If, however, you figure it out, it would be nice if you could
submit some documentation for it.

Thanks,
Dirk Herrmann
