The opAssign kills all type safety. I think only NotNull!T should be accepted... So "foo = bar" won't compile if bar is nullable. To fix, "foo = NotNull(bar)",
In both cases, the assert(x !is null), whether in opAssign or in the constructor, is going to fire, preventing the assignment. Losing the opAssign would force you to think about it, but I was concerned that it'd make it annoying to use in a case where you already know it is not null. Perhaps worth it? I'm undecided. The constructor is the important part, definitely.
