Okay, cool, then I misunderstood the point of neoscript (I thought you
would compile Python to neoscript and then neoscript to binary).

As Dan says, go for it, give it a go. I think it'll give you a very
good demonstration of how CPython, and especially PyPy, are actually
highly performant languages :)

Hmm, I didn't call on any library functions. The crucial and
time-consuming operations were entirely implemented using operators on
constants.

(I also deliberately reused the name "time" in multiple ways, just to
stress-test anything that tries to restrict data types.)

In any case, it's not Python if it can't handle arbitrarily large
numbers. Python is an excellent language for mathematics.
