Like I said, I'm not going to say anything about how Python should be. If I were going to comment on that I'd say it would be cute but possibly silly to actually add to the core. But in the math library I made some time ago there was an AbsoluteZero with the property that when you added it to x you got x for any x whatever (got used as the default additive identity for classes that didn't have an add_id defined...) > Probably they can be useful as > sentinels, but in Python I nearly never use sentinels anymore, and > they can probably give some other problems... > > Bye, > bearophile -- David C.
