Is there some advantage to this over
try:
os.unlink('missing.txt')
except OSError as exc:
do_something()
I thought the whole point was to replace code that would otherwise
contain 'except: pass' with something slightly more concise. Once you
expose the exception, it becomes just an uglier version of a try/except
block, as far as I can see.
