Re: New EEP draft: Pinning operator ^ in patterns

I'd much prefer if `^` was used to allow rebinding. But I know that would be too confusing since Elixir went with ^ to mean regular binding. So maybe `!`?

But this change just lets you add the `^` while not changing how anything works? That sounds like it'll cause a lot of confusion when reading since sometimes a bind is using `^` and sometimes they aren't but it is doing the same thing...

This is less error prone when code is being refactored and moved around so that variables previously new in a pattern may become bound, or vice versa, and makes it easier for the reader to see the intent of the code.
