Notice that I said learn, not memorize.  The key is to find a way
to learn without having to resort to rote memorization.  Most
programmers are better at learning things that have some
structure to them rather than just trying to memorize a table of
facts.  The C operators, and their precedence relationships, have
a lot of structure (a lot of which you already know) - these can
be learned, and retained, while needing to remember only very
little.  Please see the long piece I wrote responding to Ben
Bacarisse's original posting.
