How is this any different than using a mutable reference or pointer to the "T"?

  struct Pointer<T> { ptr: *mut T }
  struct Pointer<T> { ptr: &mut T }
This is just adding a ton of overhead and memory usage

You can safely pass Rc<RefCell<_>> around your program and store inside any structures without pretty much any concern for any lifetimes.
