Create a new integer object with a value of \var{ival}.
The current implementation keeps an array of integer objects for all
- integers between \code{-1} and \code{100}, when you create an int in
+ integers between \code{-5} and \code{256}, when you create an int in
that range you actually just get back a reference to the existing
object. So it should be possible to change the value of \code{1}. I
suspect the behaviour of Python in this case is undefined. :-)
