Sorry, I just cancelled an article where a rather essential part was
deleted (I just intended to move it...)  Here is next attempt -

The few times I use a**b, a and *b are usually class objects.  operator*
could be cross product or a set operation.  b.operator*() may exist too,
but to me that is less important.  To allow both this and Complex
operator**(Complex&,Complex&), I think the rule must be something like
"** is exponentiation unless that is an error".  I do not volunteer to
write the parser though.  A binary operator~ is my favorite.
