Operator does not produce type, it produces value of expression,
and type of expression happens not to be the type you expected.
But such expectations need not correspond to language rules (try
to think from from language laywer perspective). In bearophile
case, I guess Typedef!double overloads unary operator which
returns double which is primary reason for such behavior.
