qualifying object classes on the fly [message #83633]

Is there an accepted method, or an available function, for determining of an object class exists. I'd like to declare an object with the class specified as the argument to obj_new(), and if it fails to find a known class, have the object return as !null or obj_new(). This is the behavior I would like.

o = OBJ_NEW('testclass', /RETURN_NULL_ON_FAIL)

Currently, asking for a non-existent class breaks the program. Some part of me thinks it would be too inelegant to use CATCH for something like this.

Alternately, is there a routine like this:
result = TEST_OBJ_CLASS('testclass') ?

Thanks
