Tab completion / dir broken on concurrent.futures #137282
Description
Bug report
Bug description:
I just noticed that in 3.14rc1, tab completion is broken on concurrent.futures. Trying dir, I got:
>>> import concurrent.futures
>>> dir(concurrent.futures)
Traceback (most recent call last):
File "<python-input-2>", line 1, in <module>
dir(concurrent.futures)
~~~^^^^^^^^^^^^^^^^^^^^
File "/Users/henryschreiner/.local/share/uv/python/cpython-3.14.0rc1+freethreaded-macos-x86_64-none/lib/python3.14t/concurrent/futures/__init__.py", line 47, in __dir__
return __all__ + ('__author__', '__doc__')
~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
TypeError: can only concatenate list (not "tuple") to list
There's a typo in the __dir__ function; it is trying to concatenate a list and a tuple.
