I'm not advocating for it (nor against it). But the OP proposes something clear different from the example in current Python.

try:

    f = open('myfile.txt')

    s = f.readline()

    i = int(s.strip())

except OSError as err:

    print("OS error: {0}".format(err))

except ValueError:

    print("Could not convert data to an integer.")

except:

    print("Unexpected error:", sys.exc_info()[0])

    raise

```

I.e.

try:

    might_raise_OSError()

except OSError as err try:

    might_raise_ValueError()

except ValueError try:

    might_raise_other()

except:

    oh_well()

The proposal is to more concisely catch exceptions raised within the 'except' suites themselves.
