Thanks. I had managed to work it out myself, and it works now.

However, there is a problem: if I try to compile a function with guards, I 
get an error from the compiler saying "illegal guard expression". It works 
fine to compile it as usual... Any idea why?

Then there is a more general observation: it's not at all easy to navigate 
the abstract forms in order to make changes... compared to Lisp, anyway, 
because there everything is a list, here the structure is heterogenous...

regards,
Vlad
