PEP 842 proposes __export__ for controlled module visibility in Python
PEP 842 introduces a new standard for Python modules, proposing an `__export__` variable to explicitly define and limit the visibility of module members. This aims to improve code maintainability and prevent accidental reliance on internal implementation details, a common issue with current underscore-based conventions. If adopted, this PEP would affect all Python developers writing or consuming modules, providing a more robust mechanism for defining public APIs and enhancing the clarity of module interfaces. The proposal is currently in the Draft status for Python 3.16.
