[cfe-dev] Type of enum constants

If I have:

typedef enum { E } e_t;

and then an expression:

a = E;

is it possible to get back to the typedef name from the DeclRefExpr node for 'E' ?

EnumConstantDecl * EC = dyn_cast< EnumConstantDecl >( DeclRefExpr->getDecl() );

QualType = AC->getASTContext().getEnumType( dyn_cast< EnumDecl >( EC->getDeclContext() ) );

gets me to enum { E } e_t, but not the typedef itself.
