E901,E999,F821,F822,F823 are the "showstopper" flake8 issues that can halt the runtime with a SyntaxError, NameError, etc. These 5 are different from most other flake8 issues which are merely "style violations" -- useful for readability but they do not effect runtime safety.
- F821: undefined name
name - F822: undefined name
namein__all__ - F823: local variable name referenced before assignment
- E901: SyntaxError or IndentationError
- E999: SyntaxError -- failed to compile a file into an Abstract Syntax Tree
