| When setting |
| <code class="computeroutput"> |
| <a class="link" href="BOOST_PROTO_MAX_ARITY.html" title="Macro BOOST_PROTO_MAX_ARITY">BOOST_PROTO_MAX_ARITY</a> |
| </code> higher than the default, compile times |
| slow down considerably. That is due in large part to the explosion in the number of |
| <code class="computeroutput">operator()</code> overloads that must be generated for each |
| Proto expression type. By setting <code class="computeroutput">BOOST_PROTO_MAX_FUNCTION_CALL_ARITY</code> |
| lower than <code class="computeroutput"><a class="link" href="BOOST_PROTO_MAX_ARITY.html" title="Macro BOOST_PROTO_MAX_ARITY">BOOST_PROTO_MAX_ARITY</a></code>, |
| compile times can be sped up considerably. |
