For the record, I still really don't like PEP 463. We should strive to
catch fewer exceptions, not make it easier to catch them.
Can you please clarify what you are saying in the last sentence?
The first time I read it, my brain parsed it as "People should raise
fewer exceptions, i.e. use LBYL less".
Typo: I meant EAFP not LBYL - sorry!
Later it seemed more likely that you meant "The set of exceptions we
catch in a specific piece of code should not be too large; we should
only catch those exceptions that we really mean to handle".
But perhaps you mean something else altogether?
Also I don't see the connection between the first sentence and the
second. Exception-catching expressions as per PEP 463 just give you a
more concise way of of doing something you can do with try+except. Do
you mean it would make it easier to catch exceptions because you have
to type fewer characters, and that this would be a bad thing?
Thanks,
Rob Cliffe
