E.g. there's the whole lets-get-rid-of-@, and now is the 1st time I
heard there's a "dynamically sized types" proposal... well, other than
in passing in this thread, that is.
Here's the stuff we have on dynamically sized types (DSTs):

Notice that the representation changes discussed in Niko's initial
blog post are out of date. We aren't planning to do them, since there
doesn't seem to be a soundness problem with having smart pointers like
like `~` having different representations depending on what they point
to.
This will make transmuting ~ to get a * (e.g., to allocate memory for
storage in an Rc, with automatic clean-up by transmuting back to ~ on
destruction) harder to get right, won't it?
