| Use <code class="computeroutput">proto::convertible_to<></code> to match a terminal that is |
| convertible to some type. For example, the grammar |
| <code class="computeroutput"><a class="link" href="terminal.html" title="Struct template terminal">proto::terminal</a><proto::convertible_to<int> ></code> |
| will match any terminal whose argument is convertible to an integer. |
