After previous attempts at upgrading FilmoMeter to rid itself of the ungodly shackles of parameterized modules, I finally managed to pull it off today! WebMachine 1.10.1 and MochiWeb 1.5(?) finally fix this issue by removing all traces of parameterized modules. All hail functional gods!
Now I can finally upgrade to Erlang R16B and Elixir 0.9.2 in peace.
