Copying IDL objects [message #12981]

I am trying to figure out how to make a copy of an instance of an IDL object.

a = obj_new('myobj')
b = a
; This does not do what I want, it makes a new reference to the same instance

b = obj_copy(a) ; This is what I want

The only way I can see how to do it is:

pro my_obj::copy, out
out->set_a, self.a
out->set_b, self.b
....
end

This means I have to write a set_X function for each field, and each object
class needs its own version of the ::copy routine. This seems crazy.

I seem to recall a post from a few months ago about some ways of generally
getting/setting properties in IDL objects. Any ideas?
