Eval would be faster than a macro sub, but that would be slower than
an IIF or other built in VFP function as you'd have one function EVAL
firing another function MAX instead of just one function IIF().
Further that is strictly a VFP way to do it and could not be
duplicated in other backends - something IMO we should avoid if
possible.
