For something that's not a pure container, this is an anti-pattern. No

If the launcher gets installed, it will be available in PATH. IIRC,

The py launcher in Windows supports a "py.ini" file beside the
executable and in %LocalAppData%. The equivalent of the PY_PYTHON,

This message is longer than I had anticipated.
To aid comprehension, I'm:
- accepting that .split and .subgroup help my "handle some excpetions
but not others" situation, barely
- arguing for ExceptionGroups acting like other containers: truthy if
nonempty, falsey if empty; iterable; .subg
Is there a tool that (1) detects import name collisions; and (2) attempts
to read package metadata and package file checksums (maybe from the ZIP
'manifest')?
In order to:
- troubleshoot module shadowing issues
- $PATH
- sys.path
- `python -m site`
- incomplete and overlapping uninstall

You can pass an arbitrary function to eg.split() and eg.subgroup(), and
that function can have a side effect. Suppose you want to log and ignore
OSError with errno==ENOENT but re-raise the rest, you can do this:
```
def log_and_ignore(err):
if err.errno == ENOENT:
log(err)
retur
Looking at the following PEP example, I'm still not sure what he should do to
handle some but not all OSError instances:
...raise ExceptionGroup(
... "eg",
... [
... ValueError(1),
... TypeError(2),
... OSError(3),
...

I have had enough problems with this that when I do modify/replace something, I
put in a marker that I can check for explicitly. Expecting this marker to run
automatic
In earlier versions of the PEP ExceptionGroup was not immutable and split
actually removed matching exceptions from it.
It was also iterable so you could get a flat list of all the contained leaf
exceptions. Then we changed it.
ExceptionGroup is a tree of exceptions, and the internal nodes of the
18 matches
