This is not an enhancement request, it shows a language small design problem.

D gives no warnings nor errors on this code:


void main() {
    uint x;
    ubyte y = (x >> 16) && 0xFF;
}


Here to extract a ubyte the programmer has used a logical 'and' instead of a
bitwise 'and' by mistake. And it's not an uncommon mistake.

Ideas to face this kind of bugs are welcome.
