Description
Describe the bug
Trying to run pylyzer v0.0.82 on the application entry point results in 100% CPU usage and panic:
Start checking: __init__.py
thread 'sqlalchemy/sql' panicked at /home/user/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/erg_compiler-0.6.53-nightly.5/context/compare.rs:362:9:
recursion limit exceed: structural_supertype_of(Iterable(?T), List!(T, _: Nat))
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Reproducible Code
Still tracking the problematic import, unfortunately the panic occurs in the proprietary repository.
Environment
OS: Debian Linux
Version: 13 / Trixie
Expected behavior
pylyzer doesn't panic.
