I agree with that principle. It is useful to add general purpose facilities to Guile to make it better for translating other languages into.

Neil, does your code try to Ken> support multi-threaded Lisp? No, it doesn't. This is a serious issue. Multi-thread support is a usefu thing, and when we add primitives, we should preserve multi-thread support if at all possible. Can you and Guile developers work on a way to do this with multi-thread support?
