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 "<stdin>", line 1, in <module>
AttributeError: __exit__

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