   I'm using this project as third-party library to in my project. This project runs on Python 3.10, Python 3.11. The only one feature I'm use is generate SQL queries to request data from Snowflake, but project team doesn't support Python 3.9+. To improve my build quality I started run unit tests, but one or two of them failed. The issue is in new Python 3.11 commands flow who discovered the error in the extract_func_global_refs method. I rewrote it with the correct logic. Additionally I send you patch to fix source codes incompatibility with Python 3.11

   P.S.: All unit tests passed with Python 3.9, Python 3.10, Python 3.11.
