range or xrange disallowed for big numbers

Is there a reason (technical or philosophical) to disallow:
range( 10000000000L, 10000000000L + 1L )
or
xrange( 10000000000L )
etc...?
Clearly, these case are not limited by memory consumption, and
especially in the xrange case, I would think very large numbers should
be allowed (at least, reasonable ranges of very large numbers, which
can have their uses). I actually found a bug in a plotting backage,
due to this (I'll inform the authors).

Python 2.3a0 (#2, Sep 22 2002, 18:58:21)
[GCC 3.2.1 20020912 (Debian prerelease)] on linux2
>>> xrange(10000000000L)
OverflowError: long int too large to convert to int
>>> range(10000000000L, 10000000000L + 1L)
OverflowError: long int too large to convert to int

I'd be happy to prepare a patch for Python2.3 (and earlier), if it
isn't unreasonable to do.
