      <para>
        When setting
        <computeroutput>
          <macroname>BOOST_PROTO_MAX_ARITY</macroname>
        </computeroutput> higher than the default, compile times
        slow down considerably. That is due in large part to the explosion in the number of
        <computeroutput>operator()</computeroutput> overloads that must be generated for each
        Proto expression type. By setting <computeroutput>BOOST_PROTO_MAX_FUNCTION_CALL_ARITY</computeroutput>
        lower than <computeroutput><macroname>BOOST_PROTO_MAX_ARITY</macroname></computeroutput>,
        compile times can be sped up considerably.
