No, it could not work just fine. You are basically banning tuples from the
context expression (remember that the "as" clause is optional).
Maybe one could argue that this is not a problem because tuples are not
context managers anyway, but how would this work then:
i = 0 or 1
with (a, b)[i]:
Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
