Yet another numeric format? eek. If anything, we should be dropping octal,
rather than adding binary.
You want binary? Just use int("10010", 2). No need for more syntax.
I'd go for weak objects (proxies) rather than weak dictionaries.
Duplicating the dict type just to deal with weak refs seems a bit much.
But I'm not a big brain on this stuff -- I tend to skip all the
discussions people have had on this stuff. I just avoid the need for
circular refs and weak refs :-)
Most of the need for weak refs would disappear with some simple form of GC
installed. And it seems we'll have that by 1.7.
