Protocols can't be quoted?

[devinus]

defmodule Adapter do
  defmacro defadapter(name) do
    quote do
      defprotocol unquote(name) do
        def create(rec)
        def read(rec)
        def update(rec)
        def delete(rec)
        def exists?(rec)
      end
    end
  end
end

import Adapter

defadapter Adapters.Memory

defrecord Contact, id: nil, name: nil

defimpl Adapters.Memory, for: Contact do
  def create(_rec) do
  end

  def read(_rec) do
  end

  def update(_rec) do
  end

  def delete(_rec) do
  end

  def exists?(_rec) do
  end
end

Will give "behaviour Adapters.Memory undefined"

[devinus]

contents = quote do
  defprotocol Foo do
    def bar()
  end

  defimpl Foo, for: Number do
    def bar(val), do: true
  end
end

Code.eval_quoted(contents)

nofile:1: behaviour Foo undefined

It is a bug on the import hygiene mechanism. The quoted expression is using the def/2 that comes from Kernel and not the one that comes from the protocol. This is a serious bug, I need to find a way to fix it.
