  Merges the dict `b` into dict `a`.

  If one of the dict `b` entries already exists in the `dict`,
  the functions in entries in `b` have higher precedence unless a
  function is given to resolve conflicts.

  Notice this function is polymorphic as it merges dicts of any


  ## Examples

      iex> dict = Enum.into([a: 1], dict_impl.new)
      iex> Dict.fetch!(dict, :a)
      1
