It does not. Given the first statement's behavior, you would 
expect `dchar` type to mean *re-encode*, as this is what it is 
doing (this is a special compiler-generated decoding feature).

But any char element type other than char arrays int promotes. 
Subtle changes in meaning for the same syntax are bug factories. 
This is why I really like `~` being the concat operator instead 
of `+`.

If integer promotion to dchar didn't work, then you would know 
immediately what the problem is.
