I would like to add Dialyzer to the list.
And I think you should avoid pattern matching on keyword lists (it a big NO-NO in Elixir IMO), since pattern matching relies on the order of their elements. Here’s an example to show what I mean:
iex(1)> %{a: a, b: b} = %{a: 1, b: 2}
%{a: 1, b: 2}
iex(2)> %{a: a, b: b} = %{b: 2, a: 1}
%{a: 1, b: 2}
iex(3)> [a: a, b: b] = [a: 1, b: 2]
[a: 1, b: 2]
iex(4)> [a: a, b: b] = [b: 2, a: 1]
** (MatchError) no match of right hand side value: [b: 2, a: 1]
