This is an interesting angle. I've always considered "for/else" to be
unintuitive, not because of "else", but because of the coupling with "for".
Instead, I think of this as a "break/else" statement, and everything gels
for me. The same applies to my comprehension of "while/else".

I wonder how this came to be called "for/else" or "for-else". I haven't
spotted that expression in the python docs yet.

With whatever name, I find the construct quite elegant and regularly useful.
