This can be helpful in some generic contexts. E.g. struct MyBTreeSet<T: ArbitraryOrd> would be possible. (Actually, this would be neat to have in alloc.)

Note that this is a breaking change and will require 0.2.0.

This is needed to fetch a value from map (set) if one has &T. (I suggest you try to actually use this crate with BTreeMap<Ordered<T>> to evaluate how good it is.)

This is obviously unsafe and requires #[repr(transparent)] but should be obvious and trivial.

Though I'm afraid this may conflict with #1 (too little time to check). In that case IDK which one is preferable.

Though, it's a good question if they are actually useful. For instance std::num::Wrapping, which is conceptually very similar, has no methods.
