That might be useful indeed.


   typedef int const * const &RPInt;

How can I access the details of the aliased type ? Right now I'm seeing 
an LValueReference, which I can "unwrap" using clang_getPointeeType 
multiple times. Is there a way to learn about any involved cv-qualifiers ?

On a somewhat related note: I can't see any type representing arrays, 
and no way to retrieve the array size(s).
(Array parameters seem to decay to pointer types, which also looks wrong.)
