Interesting, for me, when I put it into ruote-fluo, I get :

Oh wait, let me guess, you put "engine.launch(pdef)" part with it too ?

What is not obvious about

  sequence do
    calculate_next_trajectory
    emit_trajectory

Programming is about building "higher" abstraction levels.

Lean the tool, use participants.
