   Merges the dict `dict2` into dict `dict1`.
 
   If one of the `dict2` entries is found in `dict1`, the
-  conflicting entries in `dict2` have higher precedence unless a
-  function is given to resolve conflicts.
+  conflicting entries in `dict2` have higher precedence.
 
   Notice this function is polymorphic as it merges dicts of any
   type. Each dict implementation also provides a `merge` function,


  In the examples below, `dict_impl` means a specific
  `Dict` implementation, for example `HashDict` or `Map`.

  ## Protocols


defmodule Dict do
  @moduledoc ~S"""
  This module specifies the Dict API expected to be
  implemented by different dictionaries.

  It also provides functions that redirect to the underlying
  Dict, allowing a developer to work with different Dict
  implementations using one API.

  To create a new dict, use the `new` functions defined
  by each dict type:
