1. const_reference is always a reference type.
2. This should only result in ref-to-ref if your compiler does not support
partial specialization NOR the MSVC++ workarounds (would Sun's compiler be
one of these?).

The original reason for call traits was to avoid ref-to-ref; optimization
was added later.  So it should work (?)  I don't have access to a MSVC
compiler, but just from looking at the code it looks OK AFAICT.
