There is one thing that I have missed in PEP 227: a motivation for the
proposed change. All I can find is the statement that other languages
have nested scopes. That sounds like a valid reason when designing a
new language, but is it sufficient to modify an existing language in a
way that risks breaking working code? I can't remember seeing
excessive complaints about Python's current scoping rules.
