Should I turn on/off repeatedly to reflect changes of currently developing packages?

  1. A part of source code
function reset!(clock::Clock)
    error("test")  # to check Revise.jl
    clock.t = 0.0
    return clock
end
  1. reset! gives an error

Still does not work for me.

Note: of course it works after turning off/on REPL with changes.
