New submission from Anthony Sottile <asott...@umich.edu>:
this is breaking code that's unfortunately out of my control (vendor) -- also
it looks really wrong
```python
import importlib.metadata
print('looks like a list:')
print(importlib.metadata.distribution('pip').entry_points)
print('first item:')
print(importlib.metadata.distribution('pip').entry_points[0])
```
output in 3.9:
```console
$ ./venv39/bin/python t.py
looks like a list:
[EntryPoint(name='pip', value='pip._internal.cli.main:main',
group='console_scripts'), EntryPoint(name='pip3',
value='pip._internal.cli.main:main', group='console_scripts'),
EntryPoint(name='pip3.8', value='pip._internal.cli.main:main',
group='console_scripts')]
first item:
EntryPoint(name='pip', value='pip._internal.cli.main:main',
group='console_scripts')
```
```console
$ venv310/bin/python t.py
looks like a list:
(EntryPoint(name='pip', value='pip._internal.cli.main:main',
group='console_scripts'), EntryPoint(name='pip3',
value='pip._internal.cli.main:main', group='console_scripts'),
EntryPoint(name='pip3.8', value='pip._internal.cli.main:main',
group='console_scripts'))
first item:
Traceback (most recent call last):
File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 217, in
__getitem__
return next(iter(self.select(name=name)))
StopIteration
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

raise KeyError(name)
