There is, sigh. operator,() has a special regime among operators. It's
called the /sequencing/ operator. It does that, /sequencing/, like a champ.
Pretty much nothing else. Other operators don't specify the order of
evaluation. This one (and && and ||) does. When overloading it, that
important property of operator,() is lost.
