No, there's no way to tell if a T_var has been initialised. I imagine
that calling operator->() will work with all ORBs, but the C++ mapping
says

  "The overloaded operator-> returns the T* held by the T_var, but
   retains ownership of it. Compliant applications may not call this
   function unless the T_var has been initialised with a valid
   non-null T* or T_var."

So there's no officially compliant way of checking. Oh well.

Cheers,

Duncan.
