Re: New EEP draft: Pinning operator ^ in patterns

I rarely post but this change seems strange.

The rule for Erlang has always been single assignment so I don't think
pinning is necessary.
What if we reverse the operator and call it the "rebind" operator?
Similar to how Elixir has to explicitly pin, Erlang has to explicitly
rebind.
Borrow the "spirit" and not the exact thing.
Let's call it "&" to avoid confusion.

Say in a case expression and you want to introduce a new variable, ignoring
whatever that has appeared before, use:

case thing() of
    {ok, &T} -> T
end

No new error or warning introduced
