[Python-ideas] "while ... try" - block or "for ... try" - block

[Yuval Greenfield]

I also only see trouble with this construct.

I initially assumed you meant:

    while expr try:
        # ...
    except IOError:
        print 'error'

would actually equal:

    try:
        while expr:
            # ...
    except IOError:
        print 'error'

This makes sense because the "except" is after the while loop suite so it
should mean that being in the except suite removes the possibility of
reentering the while suite.

Anyhow, because of the ambiguity, and because we'll immediately need
for/try if/try and try comprehensions (some of which have contradicting
"else" semantics) I'm -2 on this.
