      You can call this function and pass it a dictionary, or any other
      combination of arguments you could pass to built-in dict in order to
      construct a dictionary. The function will return a xlat closure that
      takes as its only argument text the string on which the substitutions
      are desired and returns a copy of text with all the substitutions
      performed.
