I use Rustpython in wasm/browser. When I try to call some async code, using asyncweb.run, I get:
Python execute error RangeError: Maximum call stack size exceeded

This error probably occurs at the line with import asyncweb.
After that it's possible to run code again but from this moment it's gives:
AttributeError: module 'asyncweb' has no attribute 'run'
and print(dir(asyncweb)) returns ['Promise', '__builtins__', '__doc__', '__loader__', '__name__', '__package__', '__spec__']
Worst thing that sometime(on first run) it works ok.
Bet If I reload page for example cmd+R, asyncweb become totally broken and impossible to get it working even with cmd+shift+R
Such behaviour also noticeable in rustpython/demo example too. To reproduce:
- Select asyncweb preset from dropdown.
- Launch it
- Try reload page cmd+R(prob, without awaiting result)
- Retry step 1 and you probably catch bug.
