[Python-ideas] Re: for ... except, with ... except

I propose to add "except" clause to "for" and "with" statement to catch exceptions in the code that can't be wrapped with "try ... except".

  for VAR in EXPR:
      BLOCK
  except EXC:
      HANDLER

should be equivalent to

  try:
      _it = iter(EXPR)
  except EXC:
      HANDLER
  else:
      while True:
          try:
              VAR = next(_it)
          except StopIteration:
              break
          except EXC:
              HANDLER
              break
          BLOCK

1. The 'for' loop can have an 'else' clause, and so can the 'try' statement. Is there any ambiguity over its meaning?
