I wonder if we shouldn't add some warning output if it has to fallback to findDeclaration so that we know if we're missing something that should be added to the cache. Or are there some known cases that aren't worth adding?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Caching the cache might be worth something as well... I don't have the time to look into this now, but I wonder if the symbol table could be used directly for the lookup since we already have the qid? This wouldn't find function-local declarations, but that could be handled specially.</p></pre>

In case it can't find anything fall back to the findDeclarations.</p>
