Actually, I guess special handling for CallExprs might make sense specifically for some of the functions in `std::meta` depending on how we want to handle those (GCC treats them as builtins)...  Yeah, I suppose we can always refactor it later if this turns out to be too much, so if you think it makes sense to keep it then we can leave it as-is.
