[Python-Dev] Multiline 'with' statement line continuation (original) (raw)

Even if it weren't a syntax error, the syntax would be ambiguous. How will you discern the meaning of::

with ( foo, bar, baz): pass Is that three separate context managers? Or is it one tuple with three items?

Is it meaningful to use "with" with a tuple, though? Because a tuple isn't a context manager with enter and exit methods. For example:

with (1,2,3): pass ... Traceback (most recent call last): File "", line 1, in AttributeError: exit

So -- although I'm not arguing for it here -- you'd be turning an code (a runtime AttributeError) into valid syntax.
