[...] if the CM provides the value before, and the with block accepts it, it can then have the exception added to it:

with trap(OSError) as cm: os.unlink('missing.txt') if cm.exc: dosomething()

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.
