This commit takes a second pass through the `std::option` module to fully stabilize any lingering methods inside of it. These items were made stable as-is * Some * None * as_mut * expect * unwrap * unwrap_or * unwrap_or_else * map * map_or * map_or_else * and_then * or_else * unwrap_or_default * Default implementation * FromIterator implementation * Copy implementation These items were made stable with modifications * iter - now returns a struct called Iter * iter_mut - now returns a struct called IterMut * into_iter - now returns a struct called IntoIter, Clone is never implemented This is a breaking change due to the modifications to the names of the iterator types returned. Code referencing the old names should updated to referencing the newer names instead. This is also a breaking change due to the fact that `IntoIter` no longer implements the `Clone` trait. These items were explicitly not stabilized * as_slice - waiting on indexing conventions * as_mut_slice - waiting on conventions with as_slice as well * cloned - the API was still just recently added * ok_or - API remains experimental * ok_or_else - API remains experimental [breaking-change]

Isn't Item the "proper" name for this iterator according to the naming conventions RFC?

Can't find the right RFC for it, if it exists, but this has always been @aturon's intention for the names to become.

While Item used to be the conventional name, we've since tweaked the conventions so the name of the iterator returned should match the name of the method of iteration.

Just FYI, I don't believe the stability attributes on methods in trait impls have any meaning.

Using a type alias for iterator implementations is fragile since this exposes the implementation to users of the iterator, and any changes could break existing code. This commit changes the iterators of `VecMap` to use proper new types, rather than type aliases. However, since it is fair-game to treat a type-alias as the aliased type, this is a: [breaking-change].

This is a breaking change due to the modifications to the names of the iterator
types returned. Code referencing the old names should updated to referencing the
newer names instead. This is also a breaking change due to the fact that
IntoIterno longer implements theClonetrait.These items were explicitly not stabilized
