Message 99866 - Python tracker (original) (raw)

All examples so far (*) have to do with our inability to have properly nested blocks. If we did, I'd make the except clause a block, and I'd issue a syntax warning or error if a nested block shadowed a variable referenced outside it. Ditto for generator expressions and comprehensions.

As long as we don't have nested blocks, I think it's okay to see the limitation on (implicit or explicit) "del" of a cell variable as a compiler deficiency and fix that deficiency.

(*) However there's also this example:

def f(): ... try: 1/0 ... except Exception as a: ... def g(): return a ... return g ... SyntaxError: can not delete variable 'a' referenced in nested scope
