This sounds nice. I think the first thing I’d do is start putting my application and top-level supervisor code in the same file (they’re generally small enough to both fit on one screen together). The second thing would be to wish that I could declare the same module in multiple files and have the compiler combine them for me:




    poke() ->
      gen_server:cast(?MODULE, poke).




    -export([init/1, handle_call/3, handle_cast/2, handle_info/2, terminate/2, code_change/3]).

    handle_cast(poke, State) ->
    %% …


After that, I’d start wondering about monkey-patching, so there’s that to watch out for.
