Is it possible to say a C-function *anything* about a datastructure's structure?
Via the C-interface of OCaml?!
If so.... at least under Mac OS-X it should be possible to solve that task
with Objective-C. It can dump objects completely.
So this - at least on this platform - would be possible then.
But IMHO this may not be possible with all Objective-C implementations.
Ciao,
