I am looking for source code for any PE system, preferably written in Haskell for a Haskell-like (sub)language.  I am aware of "The Mini-Haskell Partial Evaluator" (see http://www.math.chalmers.se/~rjmh/PECourse/Exercises/PE.html), but it currently does not seem to work with recent version(s) of Haskell [nor does the web version seem to work, even on very simple examples].

I am also aware of the extensive litterature, what I am really in search of is source code with a decent license :-).  Best of all would be some 'orphan' PE system where the author would like the system to grow, but does not have the time to do so -- I am looking at adopting...

Thanks for any help,
