It is! :-) :-)

But seriously, the function you are looking for is \object-class.
Whay is it not named \object-type ???
Because the already created objects only have a <class> associated with them.
You can only test for membership using instance?(<type>, obj), but this means
calling a function. Also this is not unique, i.e. an object can be member of may
types (think singleton, limited()).

When creating a new instance, the type supplied to make matters. This is why we have
type-for-copy.


Hope this helps,
