[fetter-devel] Couple of probably silly questions

Yes. Since the ABI details are embedded into the bindings, the ABI is
per-binding, not per-application.

QT isn't regular C++ code. Its header files, as well as any programs
that use it, are not regular C++. VZN could bind to the MOC-processed
headers, but since there is no "MOC for Lisp", Lisp programs couldn't
use the resulting library comfortably. This problem is solvable, as
Python has rather good Qt bindings, and Vzn would likely make the task
easier, but significant extra work will be required.

GCL could likely run Verrazano, but I think the problem is that it
can't run C-FFI.
