For-else/while-else are confusing. During the previous discussion even the
construct's proponents have fallen to its misleading nature. The word
"else" alone just doesn't fit its role here no matter how intricate and
carefully constructed an example is given to explain its nature or
rationale.

I believe using for/else will cause you and maintainers of your code to
make more mistakes.
