Unresolved aliases

[marcandre]

Thanks for looking at #154 so quickly ❤️

I'm afraid the issue isn't completely solved though. If the module in question is aliased, it still does not work:

defmodule EmptyMix.Example do
  alias EmptyMix.Example
  defstruct [:name]
  use TypeCheck, enable_runtime_checks: Mix.env() != :prod
  @type! t :: %__MODULE__{name: String.t()}

  @spec! hydrate(%{String.t() => any} | Example.t()) :: Example.t()
  def hydrate(%__MODULE__{} = struct), do: struct
end

$ mix compile
** (UndefinedFunctionError) function EmptyMix.Example.t/0 is undefined (function not available)
