comma operator: keep away?

:Ok, I picked a bad example.  However, many macros need to accomplish
:more than one thing and cannot do so without the aid of some such
:trickery as
:	((expr1) & 0 | (expr2))
:which is more simply expressed as
:	(expr1, expr2)

Which is an example of the weakness of the macro facility in C (one of the
most light-weight macro facilities I've ever had foisted on me).  Without
taking a position on the general value of the comma operator -- the correct
solution to this one is to improve the macro facility, not provide a
way to kludge some (but not all) cases.
