There's no reason that if these use cases become common enough to care
about, that a future version of Python couldn't increase or eliminate the
limits. It's a lot easier to remove limits (e.g. the int/long unification)
than to add them.
I'm +0 on having the limits there initially, even if they complicate the
implementation somewhat. I'm highly unlikely to ever encounter them, just as
I've never produced a long large enough to cause problems.
