There's like two cases I know > of where it's justified, both are code that return pointers, and use 0 / false > internally. I loathe if(ptr) almost as much as if(foo &bitmask) and if(!strcmp) What's wrong with "if(foo &bitmask)" (except for its whitespace of course)? It is a multi-boolean test if bitmask is essentially an array of booleans. It seems to be Normal KNF too. But !(foo & bitmask) seems to be abNormal -- (foo & bitmask) == 0 seems to be normal.
