The problem is really that if I remove the second line of:
    x[msg.which] => int x;
    x[msg.which] => int x0;
then the first
    x[msg.which] => int x;
is accepted.

So when I add the second line, I get a confusing error message about  
that, not about the first one, which seemed a legal name overload  
(though differing from C++).
