Elixir: @spec module attribute no longer accessible in 1.7

[whitepaperclip]

Current behavior

defmodule Foo do
  @spec x() :: integer()
  def x(), do: 5
  def spec(), do: @spec
end

iex> Foo.spec() #=> nil

Expected behavior

iex> Foo.spec() #=>
[
  {:spec, {:::, [line: 2], [{:x, [line: 2], nil}, {:integer, [line: 2], []}]},
   {Foo, {2, 1}}}
]

I was accessing @spec via Module.get_attribute(__MODULE__, :spec) in defmacro __before_compile__(_). Same observations.

also would love a fix for this, my precious behaves_like is broken 😭

Same here - type-checking of foreign function interface to Elixir in Elchemy relies on it
