I want to understand the reason of constructing an improper list here.

First Question: Is the usage of an improper list necessary here?:

Line 256 in 274e44f

[field, ?= | encode_value(value, encoder)]

# encoder fallback
  defp encode_pair(field, value, encoder) do
    [field, ?= | encode_value(value, encoder)]
  end

I think improper lists do not have many uses; also there are many functions that will error when given an improper list

Second Question: why this construct actually exists in Erlang?

Hi,
