I'm working on puttingn this up for Python. I'm planning on using AJAX to pass the input string to eval on the server. I.e. - you'll be limited to expressions, which is what it seems like the Ruby thing is limited to. On the other hand, with iterators, generators and list comprehensions, you can do quite a lot with eval. If anyone else is contemplating putting up something like this, let me know so we can avoijd duplicating the effort. <mike -- Mike Meyer <[EMAIL PROTECTED]> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. -- http://mail.python.org/mailman/listinfo/python-list
