In Java this is a function call. If 'a' is a type, this is an error, since you can't declare 'd' here. So... if cc-mode assumes that the code it is looking at is syntactically correct, you can always guess. But, it is a lot nicer for the user if errors are flagged. That way lies the Eclipse approach :-) Alan> Another related question: although there is no maximum bound on how far Alan> apart template/generic brackets can be, I believe that in practice, they Alan> are never that far apart (a few hundred bytes max, perhaps). Is this, in Alan> fact, the case? For Java, yeah, generally speaking. There may be exceptions. And sometimes I think you may find surprising amounts of whitespace in there. For C++, I think you are just doomed. Even if you could get the compiler to emit perfect information, it would only emit information about the code it actually saw -- not stuff in ignored #if groups.
