If you don't have the precedence rules memorized, then you should always
explicitly parenthesize to ensure that it's obvious what the order you
expect to have happen is, when combining multiple operators.  In fact, I
always use parenthesis in this case so that it was obvious what I expected
to have happen.

It's kind of like the "always use braces" rule.  So, "(*k)++", or "*l =
(*l) + 1".  So, yeah, I rely on = precedence, but usually very little else.
