available, things get much simplified.

One addition is that CompoundLiteralExpr can appear both in rvalue and lvalue
context.

operators. For example, one can now write "x + y" where x or y is a
class or enumeration type, and Clang will perform overload resolution
for "+" based on the overloaded operators it finds.

The other kinds of overloadable operators in C++ will follow this same
approach. 

Three major issues remain:
  1) We don't find member operators
  2) Since we don't have user-defined conversion operators, we can't
  call any of the built-in overloaded operators in C++ [over.built].
  3) Once we've done the semantic checks, we drop the overloaded
  operator on the floor; it doesn't get into the AST at all.

operators in C++. Overloaded operators can be called directly via
their operator-function-ids, e.g., "operator+(foo, bar)", but we don't
yet implement the semantics of operator overloading to handle, e.g.,
"foo + bar".

Implicit declaration of destructors (when necessary).

Extended Declarator to store information about parsed constructors
and destructors; this will be extended to deal with declarators that
name overloaded operators (e.g., "operator +") and user-defined
conversion operators (e.g., "operator int").

Keep track of whether a C++ class is an aggregate. Don't allow initialization of non-aggregates with initializer lists.

duplication in the handling of copy-initialization by constructor,
which occurs both for initialization of a declaration and for
overloading. The initialization code is due for some refactoring.

  class A { };
  class B : public A {

  public:
    B() : A(), m(17) { };

Some cleanup of the cast checkers. Don't canonicalize types when not needed. Use distinct diagnostics for distinct errors.
