It was pointed out to me that there is nothing in the spect that defines casting between integer types of different sizes.
For example:
auto x = cast(int)long.max;
There is nothing in the spec that says what should happen here. Of course, we all know what it should and does do. It should be spelled out.
Also I cannot find "Value Range Propagation" anywhere in the spec. Somewhat related.
