I am afraid all of those checks will slow down processing, especially the ensure_loaded?one, which is a bottleneck in earlier Erlang/OTP versions. So my suggestion is to, when we convert to a decode error, for us to not raise it in certain situations, such as UndefinedFunctionError.

@josevalim I thought that, in most cases, this init/1 function will be called at compile time, right here (unless init_mode: :runtime was used, but I think that’s only recommended for development). That’s why I didn’t mind to provide a richer error reporting 🙂

However, I wonder if I should have used Code.ensure_compiled/1 then.

Oh, I see. This is happening on init. So yeah, it looks good to me, but we do have to use ensure_compiled instead.
