I fully agree (assuming that I've understood you correctly, of which I'm
not quite sure yet). Just to be safe, let me paraphrase what I've
understood:

1. (optional, and possibly several) guard clauses at the beginning of
the function for error cases and special cases (those might contain
either an exception or returns)

2. after that, only exactly one (or no) return at the end of the function


Is this what you mean?
