(original) (raw)

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.

EVE doesn't use stock CPython, IIRC. They use a version of stackless 2,
with their own patches. 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.
