Eve is indeed based on stackless 2, and are well capable of ignoring changes they don't think they need (or were when I was working with them). At one point I seem to remember they optimised their interpreter to use singleton floating-point values, saving large quantities of memory by having only one floating-point zero.

If a company is willing to patch python itself, I don't think their practices should be cited without more context about what they actually modified. > Victor _> ________________________ > Python-Dev mailing list > Python-Dev at python.org > https://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: https://mail.python.org/mailman/options/python-dev/tritium- > list%40sdamon.com
