Value range analysis could be extended to cover this case too:


void main() {
    ulong x = 10_000_000;
    uint y = (x <= uint.max) ? x : 0;
}


dmd 2.066alpha gives:

test.d(3,14): Error: cannot implicitly convert expression (x <= 4294967295LU ?
x : 0LU) of type ulong to uint

This is a long way beyond current VRP.
