It seems that arithmetic operators also work on booleans so I guess the
operator list above is either not correct or this is a bug.

    auto q = true + true + true;
    writefln("%s %s", true + true + true, q);

gives 
   "3 3"

but I was expecting that the form "<expression> <arithmetic-op>
<expression>" where either <expression> is a boolean result would be a
syntax error. Instead, it seems to be implicitly casting the boolean to an
int before the operation is examined.
