I have very powerful and elegant programming with CORBA interfaces too.
;-) Also as Martin mentioned, reference counting works wonders in simple
cases, but gets very nasty in medium to complex cases. I've seem some
COM Interface code where they had to resort to using raw Pointer types
etc to try and avoid reference counting and causing unexpected memory
leaks. No such problems with CORBA Interfaces.
You can obviously implement your own reference counted CORBA interface
for the simple cases too. So you have the best of both worlds I guess,
but when using CORBA Interfaces, I would avoid mixing reference
counted and non-reference counted interfaces.
