Wasn't the original design for these operators in whichever 
language started them actually the swapped form? In any case, I'd 
personally choose to warn against any operator sequence without 
separating whitespaces if the sequence isn't in fact one operator 
(like "=!" (non-warn: "= !") vs "!=", and "=&", and a lot others, 
given operator overloading).

Looking again, it's mostly the fault of OpAssign operators, isn't 
it?
