I don't really care too much about the macro-or-function side of this,
but if you wanted to improve debuggability avoiding the performance cost
of a function call, you could use a static inline function, which is
supposed (AFAIK) to have performance characteristics equivalent to those
of a macro. But again I'm not voting either way and I'm not in a
position to do the legwork either.
