This is a thread-safe reference-counted smart pointer with weak references.

How is it different from Arc<T>?

The weak references don't prevent mutable access to the inner value, Strong::borrow_mut will always succeed as long as there is a single Strong<T> handle to the value that should be mutated.

How can I help?

Improve documentation, review the code (most importantly the atomic operations), make use of it.
