Yes I do. The Lit Window Library allows this.
// get the type definition for the class foobar
prop_t aType = get_prop_type_by_name("foobar");
// create an object on the heap
accessor a = create_object(aType);
// access member variable foobar.m_string
cout << a.get_aggregate()["m_string"] << endl;
// cast the generic accessor to a typed accessor
// copy the contents of the object to a different object
// destroy the object
// a.destroy() is an alternative way of destroying it
BTW, the base part of the lit window library does not contain any GUI
code at all and is meant to be used independently for any kind of

http://www.litwindow.com/library does this. The documentation is
certainly not yet up to par, but the functionality is there and is
pretty mature already, except for container support. This is still
pretty spotty for any container other than stl::vector.
Regards and I'd love to hear any comments on my code.
