Elixir: remove multiple k/v pairs from a map

If you need to delete multiple entries in a map when using Elixir you can look at the Map module. On the Map module exists a function drop/2. The two arguments it takes are:

1. A map to delete the entry from
2. A list of keys to remove from the map

In practice that looks like this:

iex(7)> map = %{k1: :v1, k2: :v2, k3: :v3}
%{k1: :v1, k2: :v2, k3: :v3}
iex(8)> Map.drop(map, [:k2, :k1])
%{k3: :v3}

In the event you need to remove a single k/v pair there is a delete function on the Map module that can be utilized. I review that here.
