That is indeed the idiomatic way of handling the original poster's use
case without nesting a second try block.

Any proposals for new dedicated syntax should probably go to
python-ideas rather than here though. (It's a rare enough use case that
I don't like the original poster's chances of getting much support for
changes though)
