It arguably should be, but it's pretty common in C/C++ to get
uint.max with -1, and I suspect that it's fairly common in D as
well even though you could just use uint.max. So, it could be
argued either way.

I'd like to see these kinds of potential mistakes to be forced to
use something like uint.max. Of course, at this point it might be
too late to introduce something as breaking as this, but these
kinds of things should definitely be forced by the language, or
made a warning at least, pointing to the use of .max instead.
