For example of such a tool.

Check out the newest 2.0beta demo...

I'm in the midst of finishing up graduating, so I have very little
time to work on ASDL these days, but it be great if some ambitious
hacker would be willing to help keep it up to date and maintained.


<btw>
The Java serialization interface also provides similar functionality as the
Modula-3 pickling interface. Python, OCaml and to some extend SML/NJ and
Haskell have similar support. Unfortunately all the various pickle formats
are incompatible, so you can't for instance read Python pickle in Java or
vice versa. This is one problem which ASDL tries to solve.
