Thanks for asking. I don't really have much first hand experience here (which is why I asked in the first place), and that phrase doesn't immediately ring a bell.
Factor has reflection, continuations, optional typing, and meta-programming features. It supports functional, OO, and dataflow programming; it can do concurrency in a few different ways, it has excellent support for lazy lists and PEGs, and yes it even has named variables if one really wants them. The full image (including IDE and some quite featureful libraries like a relational DB, XML parser, and http server/client) is about 30K lines of code I believe, and unlike Squeak it's quite easy to trim it down for release as a standalone application if so desired. I don't use it everyday, but I haven't yet found anything enormously problematic about it. I'd be happy to admit that my perspective is probably narrower than it could be, though: I'll defer to the more experienced. - Max On Sat, May 8, 2010 at 5:03 PM, Alan Kay <alan.n...@yahoo.com> wrote: > Hi Max, > > Well, what properties do you think might be "enormously problematic" with > stack languages ....? > > Cheers, > > Alan > > ------------------------------ > *From:* Max OrHai <max.or...@gmail.com> > > *To:* Fundamentals of New Computing <fonc@vpri.org> > *Sent:* Sat, May 8, 2010 4:49:14 PM > *Subject:* [fonc] Other interesting projects? > > Hello all. > > I'm an undergraduate student (formerly CS, now math) and I've been > reading this list since the beginning of the STEPS project: this is > one of the most promising things I'm aware of going on in computing > right now.
