Replying to myself to #3:

Yes, there seems to be:

Replying myself to #2

No, it does not seem to help.

MethodError(App.TweetsController.index, (), 0x0000000000005c6c)
ERROR: MethodError: no method matching index()
The applicable method may be too new: running in world age 23660, while current world is 23678.
Closest candidates are:
  index() at /Users/adrian/Dropbox/Projects/tweet_stats/app/resources/tweets/controller.jl:7 (method too new to be called from this world context.)

function index() :: HttpServer.Response
  ...
end

Looks like I need to start refactoring the way I load routes and controllers so they’re known to Julia at compile time.

@mbauman Thank’s so much for your help!
