isImplicitlyConvertible!(int,ulong) is true. Maybe this is just

implicit conversion from a signed to an unsigned type possible?
The other way round would be at least somewhat understandable
if there's a static check that the values actually fit.
IIRC, the way they put it is that "information is not lost," so
you could always cast back to an int and get the original value.
The same is not true for casting to a smaller type, e.g. int to
byte, the original value may be lost.
