In case you didn't notice, the and-or simulation is a hack, it is not
to be used by anyone writing real code (instead of for an entry to
Obfuscated Python Code Contest) to substitute it for inline if. If
inline if is "formalized", that means the language encourages the use
of inline if, which we don't want to have.
