   <li>Type-checking for explicit conversions: currently follows C semantics, not C++ semantics.</li>
   <li>Type-checking for copy assignment: Clang parses overloaded copy-assignment operators, but they aren't used as part of assignment syntax ("a = b").</li>
   <li>Qualified member references: C++ supports qualified member references such as <code>x-&gt;Base::foo</code>, but Clang has no parsing or semantic analysis for them.</li>
-  <li>Virtual functions: Clang parses <code>virtual</code> and attaches it to the AST. However, it does not determine whether a given function overrides a virtual function in a base class, nor does it determine when a class is abstract.</li>

   <li>Implicit definitions of special member functions: Clang implicitly declares the various special member functions (default constructor, copy constructor, copy assignment operator, destructor) when necessary, but is not yet able to provide definitions for these functions.</li>
   <li>Parsing and AST representations of friend classes and functions</li>
   <li>AST representation for implicit C++ conversions: implicit conversions that involve non-trivial operations (e.g., invoking a user-defined conversion function, performing a base-to-derived or derived-to-base conversion) need explicit representation in Clang's AST.</li>
