A better (and of course *vastly* more powerful but unfortunately only a dream ;-) is a similarly limited python virutal machine..... It could make embedding python a lot simpler for lots of applications and even 'embedded python' a lot simpler. (Not to mention 'restricted execution' - e.g. for applets in web pages) *Perhaps* the pypy core will be a bit like this - but it's design goals are very different of course. Anyway, little point in wishing on a dream - I'm certainly not up to the job :-) Regards, Fuzzy http://www.voidspace.org.uk/python/index.shtml -- http://mail.python.org/mailman/listinfo/python-list
