Check for entry points correctness?

[wimglenn]

I put a wheel at https://test.pypi.org/project/issue40/#files which build was happy to build, twine was happy to push, and check-wheel-contents is happy with:

$ pip download issue40 --index-url=https://test.pypi.org/simple
...
$ check-wheel-contents issue40-0.0.1-py3-none-any.whl 
issue40-0.0.1-py3-none-any.whl: OK

Pip is happy to install it and create its console script entrypoint

$ pip install ./issue40-0.0.1-py3-none-any.whl
Processing ./issue40-0.0.1-py3-none-any.whl
Installing collected packages: issue40
Successfully installed issue40-0.0.1
$ cat .venv/lib/python3.12/site-packages/issue40-0.0.1.dist-info/entry_points.txt 
[console_scripts]
hello = mypkg:hello_world
$ cat .venv/lib/python3.12/site-packages/mypkg/__init__.py 
def helloworld():
    print("hello, world!!")

But it has a problem - typo in the entrypoint, or maybe a function was renamed and forgetting to also rename the metadata in the toml at the same time:

$ hello
Traceback (most recent call last):
  File "/private/tmp/i/.venv/bin/hello", line 5, in <module>
    from mypkg import hello_world
ImportError: cannot import name 'hello_world' from 'mypkg' (/private/tmp/i/.venv/lib/python3.12/site-packages/mypkg/__init__.py). Did you mean: 'helloworld'?

Do you think this is something in scope for check-wheel-contents? Some warning or info if they don't appear to resolve somewhere sensible within the package? It could use some static analysis (ast) so that it doesn't need to import any code to look for that.

Here is a source tree to create this wheel
