</div></div>While breakage is possible (and worthy of caution),<br>
shouldVisitImplicitDeclarations() was added just a week ago. As one<br>
of its users, I'd happily pay the price of updating my code if it<br>
meant avoiding a misleading function name. (One of those eternal<br>
tradeoffs: the more specific a name is, the more resistant it is to<br>
future changes.)<br>
<br>
That said, I don't have a good suggestion for a name;<br>
shouldVisitImplicitCode, maybe. By the time we cover declarations and<br>
expressions, there's not a whole lot left (well, other statements, I<br>
guess, but why make the name so specific that it rules that out).</blockquote><div><br></div></div></div><div>OK, shouldVisitImplicitCode sounds reasonable.</div></div>
