Dunno. Is it only me feeling the itch to remove the redundant-looking +
sign?
>>> int("-0x80000000", 0) == 0x80000000
True
Is that the equality you want to bury somewhere in a script? The fact that
the int() argument probably is a variable rather than a string constant
makes it only worse.
I'd say there is one more reason to look forward to Python 2.4.
