but still:
a, b | c
will be
a, (b | c)
and not what we want:
(a, b) | c
Gosh if you could make that work, I want that!

It's possible using expression templates. (but not easy.)
You build a tuple of
tuple< commaOperator, a, tuple<orOperator, b, c> >
as you evaluate the expression,
in the operator=(), you'd then parse the tuple.
but you'd have to parse the tuple for the commaOperator, and either build a
new tuple, or just evaluate it with some special case code.
tuple< orOperator, tuple<commaOperator, a, b>, c>;
Definitely ugly stuff. (And it may surprise experienced users because the
order of operations, is left to right, not in C/C++ priority.)
