The second part of number 2, is of course, bogus.  What I
really mean is something more like

2. Expression evaluation should honor explicit parentheses:
   parenthesized subexpressions should always be fully
   evaluated (including side effects) before their value is
   used.

And now that I think about it, Keith is right as well: the
question of order-of-evaluation is somewhat orthogonal to
the precedence + associativity question.  Sigh.  I'm
confused.  Give me a bit to sort this all out.
