URI.encode_query/1 and lists
http://elixir-lang.org/docs/stable/elixir/URI.html#encode_query/1
# current behaviour
iex> URI.encode_query(%{"some" => ["one", "two"]})
** (ArgumentError) encode_query/1 values cannot be lists, got: ["one", "two"]
# expected behaviour
iex> URI.encode_query(%{"some" => ["one", "two"]})
"some[]=one&some[]=two"
Why lists are forbidden in this method?

iex(2)> Plug.Conn.Query.encode(%{a: [1,2,3]})
"a[]=1&a[]=2&a[]=3"
iex(3)> Plug.Conn.Query.decode(v())
%{"a" => ["1", "2", "3"]}

Thanks for double-shaming me! 
Yeah, I should just go watch a movie and do that on a more fresh head. Thanks a lot. Really.

I knew I had answered this before and searched to find it
No apology necessary. I know what it’s like to be coding late and/or uncaffeinated
