+ * qualified.
+ *
+ * This file contains classes that mirror the standard AST classes for C++, but
+ * these classes are only concerned with naming. The other difference is that
+ * these classes don't use the `ResolveClass.qll` mechanisms like
+ * `unresolveElement` because these classes should eventually be part of the
+ * implementation of `ResolveClass.qll`, allowing it to match up classes when
+ * their qualified names and parameters match.
