one wasmtime dependency and a self contained python file with 100 loc seems reasonable!

much better than calling deno, at least if you have no pip dependencies...

just had to update to new api:

# store.add_fuel(fuel) store.set_fuel(fuel) fuel_consumed=fuel-store.get_fuel()

and it works!!

time to hello world: hello_wasm_python311.py 0.20s user 0.03s system 97% cpu 0.234 total

I was interested in how this compares in a kind of absolute sense. For comparison, an optimized C hello world program gave these results using `perf` on my Dell XPS 13 laptop:

       0.000636230 seconds time elapsed
       0.000759000 seconds user
       0.000000000 seconds sys

(Yes I used percentages to underscore how big the difference is. It's 368x and 209x respectively. That's huge.)

Begrudgingly, here are the standard Python numbers:

    real    0m0.019s
    user    0m0.015s
    sys     0m0.004s

it's pretty difficult to package native python dependencies for wasmtime or other wasi runtimes, e.g. lxml

Great, thanks for your post! I got it working too. This is going to be incredibly handy.
