[Python-ideas] with ... except

A common pattern for me is to write a with statement for resource
cleanup, but also handle specific errors after that. Right now, this is
a bit cumbersome:
with open("somefile", "rb)" as f:
# do something else, perhaps actually create the file
# do something else, perhaps clean up some internal cache
How about adding syntax sugar for the above, in the form of a with ...
except clause? It would nicely reduce spurious indentation, as with
the try / except / finally which, long ago(!), helped reduce
indentation and typing by removing the need to nest a try / except
inside a try / finally.
