-.. _cpydiff_core_import___all__:
-
-__all__ attribute of modules/packages isn't processed by Pycopy
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-**Cause:** Pycopy employs simplified model, where ``from mod import *`` imports all names, except those starting with an underscore. This handling is compatible with CPython.
-
-**Workaround:** Don't rely on __all__. For symbols which you don't want to be imported with ``from mod import *``, start their names with ``_``. You can still import such a symbol explicitly with ``from mod import _sym``.

-Sample code::
-
- from modules.modall import *

- print([name for name in dir() if "foo" in name])
