My language, and the problems there might be in adopting the CPython style of passing pointers around. (Another problem I've just realised is that everything in my language is mutable: I can even change the the bits of a small integer in-place. That will be interesting to solve.) (I came into this trying to investigate why CPython was so slow, I may end up wondering how it manages to be as fast as it is!) -- Bartc -- https://mail.python.org/mailman/listinfo/python-list
