|Hm, what about using FL_USER7? More generally, is there any 
|unused flag left?

Unfortunately, there's no bit available for all objects.  All flag
bits are used to represent NODEs' line number.

By the way, I still don't know why the inlined function is faster than
the simple macro.  Does anybody reveal the secret for me?
