Hi all,

The TPHOL's 08 paper "Imperative Functional Programming with
Isabelle/HOL" describes some features that
are not contained in the Isabelle2009-1 distribution
(src/HOL/ImperativeHOL).

For example, the datatype definition for a linked list does not work out
of the box,
it gives the error that \alpha node is not in heap-typeclass.

Moreover, there is no implementation of the mentioned MREC-combinator.
Also, I cannot find the described examples (SAT-checker,
Bytecode-verifier) anywhere.

Is there a more complete implementation? Is it available? Are the
examples available?

Regards,
Peter

Hello Peter,

The Linked List example and the MREC combinator are already since
December 2009 (changeset 1a82e2e29d67) in the development snapshot.

The Sat-checker and the Bytecode-verifier are still in another
repository. If you are interested, we can give you those files.
If you want to continue working on those, i.e. the SAT checker would be
a perfect example for the new Collection framework (e.g. the clauses are
sets implemented by sorted lists at the moment), I would suggest to turn
these files into a new AFP entry.

Happy Easter wishes,

Lukas
