I just want to add that I've adapted and extended Thomas' original patch for the 0o123 syntax. It should be pretty complete.

Open issues would probably be: - should int("0755", 0) give 0o755? (IMO yes) The PEP covers this, with the answer current of "yes" for 2.6 and "exception" for 3.0. (It presumes int(x, 0) should be the same as the compiler tokenizer result.)

It isn't. We already said that int() should continue to accept "0x" and "0X" prefixes for hexadecimal, for instance.

- what should "%#o" % 100 result in? "0144" or "0o144"? - should oct(100) return "0144" or "0o144"? Thanks! I missed that the formatter had the '#' option, and completely forgot about the oct() function. I think TOOWTDI says 0o144 in both cases.

I agree.
