You really should know the precedence of at least the common
operators. For instance, I don't think that there's much excuse
for code like
if((a == b) && (c != d))
Unfortunately I've come across a few cases (and in dmd too)
where compiles it wrong if you don't and get
unwanted/unexpected/buggy behavior; So the code looks similar to
that (but not by choice).
I 'think' it was something like 'if(a + 2 > b)', but I'd have to
dig them out to know for among hundreds of lines of code.
The exact order of precedence has always eluded me and are a set
of rules I'll never completely remember. However I do know that
multiplication and division are above addition and subtraction,
which is the only real place I've come to rely on it a few times
to remove excess parentheses.
