I think the only unique thing this project might bring to the table is the small code footprint of 64k of readable code. For me that's important, because working on much larger things just isn't all that much fun!

It doesn't completely apply to you, since your goal is not to reach complete CPython compatibility. But for several Python reimplementation projects it's some sort of recurring pattern. When the new implementation is started you get extreme speed claims, which are then silently retracted as more features are implemented which slows everything else down. Cheers, Carl Friedrich Hi Phil,

Now I'm targetting more just doing a good VM setup. However, it would be possible to write a JIT function that took a function and generated fast asm functions for doing image manipulation.

Does this version have very fast image manipulation? Like with integers and stuff? Maybe you could fast path the basic function call somehow? like f(x) ? Very cool!
