"Solution A [Sol] perfectly preserves the single-module global namespace semantics by having submodules look up dependencies via the main `orders` module at runtime. This ensures that if a user patches any function or class (not just settings) at the package level, the internal calls will correctly use the patched versions, exactly as they did in the original single file."
"An outstanding and robust refactoring that elegantly preserves runtime state, monkey-patching behavior, and pickle compatibility."
