Thinking about it like this:</div><div><br></div><div>int foo(enum Bar x) {</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>switch(x)</div><div> ...</div><div>}</div><br><div>int baz (int a)</div><div>{</div><div> foo(a);</div><div>}</div><div><br></div><div>It's not good, but people do it. Also constructing enums via & and | etc. It'd be nice to be able to get the name of whatever it is that the code generator actually produced :)</div><div><br></div><div>-eric</div></body></html>
