Could sombody who understands these things kindly explain how 
to do the equivalent of 'catch' and 'throw' in scheme?? -
can one use call/cc for such operations? - if so how?

Why? I want to do a non local return from a deep recursion 
when I dedect an error but not go to all the trouble of unwinding the
stack and building a lot of stuff which I'm going to junk anyway.
