The ``_ast`` module uses again a global state. Using a module state per
|
||||
module instance is causing subtle practical problems. For example, the
|
||||
Mercurial project replaces the ``__import__()`` function to implement lazy
|
||||
import, whereas Python expected that ``import _ast`` always return a fully
|
||||
initialized ``_ast`` module.

The ``_ast`` module uses again a global state. Using a module state per module

instance is causing subtle practical problems. For example, the Mercurial

whereas Python expected that ``import _ast`` always return a fully initialized
