The problem I have with Enum.count_by/2 is that I wouldn't be able just by
looking at the name to
tell it apart from Enum.count/2 which takes a function as a second argument
How will this function work with enumerables other than lists? the way it
currently does is correct?
iex(6)> Enum.tally %{a: 1, b: 2}
%{{:a, 1} => 1, {:b, 2} => 1}
