Oh, list(integer) trick would do the trick. Thanks!
However, I think then it gives incorrect info. For example, as I use Stream, it does not have all functions of List.
Enum.t is just Enumerable.t (ref) and I guess Enumerable.t is defined from Protocol (ref). It looks like it is possible to pass @t when using defprotocol - but I’m not sure it is possible to pass type parameter down to that part. Hm.
