Hmm, this seems to be something of a matter of taste.
Because of the way a^b is typeset, I don't think A^{-B + C} is
ambiguous -- I don't think it can be interpreted as A^{-B} + C or
something else. So the parentheses are optional, aren't they?
When the exponent is a long expression, it seems like A^{(expr)}
is reasonable. But if it is short, then the parentheses are cluttering.
Other opinions?
