Alex,  I think I sense what you're suggesting here (checking argument
and return types, I think), but I don't know how to do that with a
script and even then, how could one tell what is being done inside the
function in terms of memory allocation or just pointers assigned to
existing memory, i.e. no ref. count increase ?
