Env Variable to Auto-Name and Recognize __pycache__ As .__pycache__

Feature or enhancement

Proposal:

Introduce a Bash environment variable (PYTHON_PYCACHE_HIDDEN) that, when set, automatically names and recognizes the __pycache__ directory as .__pycache__. This change aims to improve directory cleanliness by making the __pycache__ directory hidden by default, reducing visual clutter in project directories.

The __pycache__ directory, often clutters project directories. While necessary for Python's efficient execution, it can be an eyesore, especially in larger projects. Making this directory hidden by default would: improve directory readability, maintain compiled functionality, and introduce optional visibility.

Bottom line, __pycache__ directory enhances Python's execution efficiency by storing compiled bytecode, but its contents are rarely useful for regular viewing, cluttering project directories unnecessarily.

El issue no menciona archivos, pruebas ni puntos de entrada. Primero localiza cómo CPython gestiona la denominación y el reconocimiento del directorio pycache, y después identifica cómo se procesan las variables de entorno. Se considera terminado cuando una configuración opcional PYTHON_PYCACHE_HIDDEN usa y reconoce de forma coherente .pycache sin romper el comportamiento del bytecode compilado.
