[webkit-dev] !!Tests for equality comparison

Hello C++ fans!

The C++ style check currently say:
Tests for true/false, null/non-null, and zero/non-zero should all be done without equality comparisons

I totally agree for booleans and pointers… but not for integers. I know it’s pretty much the same thing, but I it takes me slightly longer to process code like this:

int numTestsForEqualityComparison = 0:
// Count ‘em!
// …
if (!numTestsForEqualityComparison)
  printf(“Good job!”);

I read it as “if not number of tests for equality comparison”. That's weird. It takes me every slightly longer to think about, and I’ve gotten it wrong a bunch of times already. I’m not trying to check for “notness", I’m trying to say “if there were zero tests for equality comparison”, a.k.a.:

if (numTestsForEqualityComparison == 0)
  printf(“Good job!”);

So how about the C++ style let me just say that? I’m not suggesting we advise using that style for integers everywhere, I’m just saying it should be acceptable to check zero/non-zero using equality comparison.

!!Thanks (i.e. many thanks),


p.s.: With you I am, fans of Yoda comparison, but for another day this will be.
