* "Go to definition" does not work within the `scope` of a Phoenix router

Is there a GH issue for this already?

Any clue why it doesn't work?

Go To Definition also does not work for elixir source code.

Any clue why it doesn't work?

@Sleepful Phoenix Router macros mess with modules in scopes. e.g. in

scope "/", Foo.Bar do
    pipe_through :browser

    scope "/some" do
      get "/:id", MyController, :index
    end
end

MyController is transformed to Foo.Bar.MyController. To make it work someone would need to write a phoenix plugin to elixir_sense or add some hacks to ElixirSense.MetadataBuilder to make it understand how those macros work.
If you use a full module name (or properly alias it), then go to definition should work (not sure if router would still work though)
