As a quick reminder, PEP 409 allows this:
try:
...
except AnError:
raise SomeOtherError from None
so that if the exception is not caught, we get the traditional single exception
traceback, instead of the new:
During handling of the above exception, another exception occurred
My question:
How do we go about putting this in the stdlib? Is this one of the occasions where we don't do it unless we're modifying
a module already for some other reason?
For that matter, should we?
Pros: Makes tracebacks much less confusing, especially coming from a library
Cons: Could hide bugs unrelated to what is being caught and transformed
