AttributeError: 'frozenset' object has no attribute 'append'

Just setup a venv and "pip install coconut". Tried one of the examples in the tutorial and got many many lines of error.

~$ source coconut/bin/activate
(coconut) ~$ cd python/coconut/
(coconut) ~$ bin/coconut
Coconut Interpreter v3.0.3 (Python 3.12):

(you should report this at https://github.com/evhub/coconut/issues/new)
Coconut exiting with error: AttributeError

(coconut) $ python --version
Python 3.12.0

Same thin happens every time so repro is easy. Let me know if you need additional information or the complete traceback.

Yep; I'm well aware of this problem—I'll try to get out a new coconut version that fixes it soon. It has to do with an incompatibility between the current released coconut and the current released cPyparsing, so you can solve the issue by downgrading cPyparsing with:

pip install cPyparsing==2.4.7.2.2.1

Thank you for the quick response and the solution! Worked perfectly.
I was going through coconut withdrawal! :-)
