  \item Large octal and hex literals such as
! 0xffffffff now trigger a \exception{FutureWarning} because currently
  they're stored as 32-bit numbers and result in a negative value, but
! in Python 2.4 they'll become positive long integers.  
  
  \item You can no longer disable assertions by assigning to \code{__debug__}.

  \item Large octal and hex literals such as
! \code{0xffffffff} now trigger a \exception{FutureWarning}. Currently
  they're stored as 32-bit numbers and result in a negative value, but
! in Python 2.4 they'll become positive long integers. 
! 
! There are a few ways to fix this warning.  If you really need a
! positive number, just add an \samp{L} to the end of the literal.  If
! you're trying to get a 32-bit integer with low bits set and have
! previously used an expression such as \code{~(1 << 31)}, it's probably
! clearest to start with all bits set and clear the desired upper bits.
! For example, to clear just the top bit (bit 31), you could write
! \code{0xffffffffL {\&}{\textasciitilde}(1L<<31)}.
