For the record, this thread did prompt me to consider the new construct anew, but on reflection, I still consider it a reasonable addition to contextlib. It substantially improves the simple cases it is intended to help with, and, if anything, makes overly broad exception suppression more obviously dubious (because the name of the construct doesn't match the consequences for multi-line suites). Why? Anyone can still write "try ... except".

True, but Raymond's example of

 with ignore(OSError):
     os.remove('somefile')

struck a chord -- I've used the try ... except version of that many times, and each time it's been a pain. I now agree this context manager is a win.
