Larry, you're not the only one! (Even if others may unkindly suspect we do
it because we don't know the precedence rules...)

This reminds me of an age-old habit.  I tend to use parenthesis,
whether I need them or not, on a lot of expressions like:

 a =  b + c * d;

Not only are there languages in the world (APL and Pascal
to name two I know) that don't evaluate this in the same way C and
Java do, there remains the question not only "does the programmer
remember the precedence rules" but also "did he really
intend to rely on precedence, or did he leave out the
parenthesis he needed".   I say "he" here because "he" is
usually "me" when I puzzle over code I wrote a few years back.

So, while I usually don't do it for a few cases (-> in C, . in Java)
I tend to use a lot more parenthesis than actually required so
that I know, explicitly, what I was trying to do three years later.
