Is it your intention to support all of Python's syntax and semantics, or is this an unrelated language with mandatory strict type tags and a severely restricted set of data types? For instance, can your neos compile this code? def power(): return (2**3**4**2) % 1000000000 from time import time start = time() print(power()) time = time() - start print("Took %s seconds" % time) On my system, I get this from CPython 3.10: 176561152 Took 0.1589798927307129 seconds And this from PyPy: 176561152 Took 0.0233387947083 seconds > I envision this implementation to be significantly faster than the currently > extant Python implementations (which isn't a stretch given how poorly they > perform). Riiiiiight, yep, all existing Python implementations are terribly slow. Go ahead then; run the code above, show me a better time, and of course compare to what a recent off-the-shelf CPython can do on the same hardware. Then see how PyPy performs at the same job. > Sample neos session (parsing a fibonacci program, neoscript rather than > Python in this case): Is neoscript an intermediate language like RPython, used only to implement the compiler, or are you actually transforming Python code into neoscript?
