Hello everybody, I thought I should let you know there is progress on "Psyco", my Python specializing compiler. http://homepages.ulb.ac.be/~arigo/psyco In particular, have a look at http://homepages.ulb.ac.be/~arigo/psyco/ISSUES.txt where I give some hints about how this could be used in a more general setting. A bientôt, Armin.
