1. Please start with reading about the difference between use, import, and require in Elixir.

We use import whenever we want to easily access functions or macros from other modules without using the fully-qualified name.

So no, use should not be used here: import should. Other way round would be to define commands as macros and require them, or write an ad-hoc function generation inside __using__ macro of NewCommands and only then use it.

1. I did not dig into the code, but I guess you want Matcher to be automatically respawned is something went wrong and it crashed, right? Erlang philosophy is “crash soon,” hence instead of cumbersome error handling we just let the process crash. Aftwerwards, if you still want to match, it should be respawned, to serve further requests.

Also, it is used as a dispatcher before Commands.
