Statically typed concatenative programming may be at the point that lazy functional programming was a few years ago. As valuable as separate research and hobby projects are, at some point we should probably put our heads together and collaborate on a single vision.
I’m more than willing to lead the effort if there’s enough interest—but as it is, it seems like those most interested in seeing it happen are those least interested in actually helping. So I just keep working on Kitten.
Factor is an impressive piece of engineering, and for those who like dynamic typing, I’d strongly encourage people to use it, and see how useful a dynamic and reflective programming environment can be. It’s just not the language I want to build.
