It's not me you have to convince, it's the SC.
I personally don't want to debate this again -- if I tried to articulate my
arguments, people would just try to come up with counter-arguments, and I'd
be forced into a debate I have no interest in.
If you wanted to sway me, maybe you could write a static analyzer that
tries to measure what fraction of try/except statements have exactly this
form:
try:
some_var = some_expression
except SomeException:
some_var = some_other_expression
You can probably piggyback that on an existing static analyzer like flake8
or pylint. And for your corpus you could download the 1000 most popular
packages from PyPI (
https://github.com/python/cpython/blob/master/Tools/peg_generator/scripts/download_pypi_packages.py
).
