Consider this example, which I wrote without really thinking about it when updating something else:

var x: int;

if x == none {
  writeln("it is none");
} else {
  writeln("it is not none");
}

It results in a type error because we can't compare none and int.

However since none is the only value of the type nothing, it seems to me that any value of any type other than nothing (note 1) should compare as not equal.

note 1: any type other than nothing or potentially dtAny if it is possible to get at that in user code.
