Warning: this clause cannot match because a previous clause at line X always matches

[fourcube]

Thank you for this great library. I have one question:

pipe_matching x, {:ok, x},
      {:ok, source_dir}
      |> build
      |> tag(name, version)
      |> save(dest_dir)
      |> delete_image

leads to this compiler warning:

warning: this clause cannot match because a previous clause at line 1 always matches

Am I doing something wrong or do I simply have to live with this warning?

Hm... this didn't happen with my previous examples. (That's the perfect use
case, and exactly why I built it. :) )
