I independently came up with this same idea.  I think the concept is right,
but the syntax is lousy -- it's too easy to add/delete that comma and
accidentally change the meaning of the declaration.

Also, in C++ the comma is optional (Bjarne wanted it to be forbidden, but
X3J11 made him fix it).  It would not be wise to make a syntax change to C
that is in direct conflict with existing practice in C++.

(Meanwhile, lobby your lint vendor for a /*MONOMORPHIC*/ lintpragma that will
check this for you.)
