I'd be interested in a description of how it's unique. I like that there are integer range types, though it's very hard to check statically that a value is guaranteed to be in the permitted range. The other parts of Ada's type system that I've encountered seem pretty standard, though I know there are parts that I haven't looked at and don't understand.
