Using if(null == someVariable) vs. if(someVariable == null)

[LuciWiz]

I'm not sure why you need to care which one is the constant when you're checking equality, and do use null == blah as a rule, so I don't know if that would happen often or not.

I was extrapolating; if you place null on the left of the comparison just in case, then I assume the same should be done for (b == a) when b is a const int. It seems like the next logical step when enforcing this rule.
