xscanf(x, format,  pointer1, pointer2, .... pointern) is not directly
possible in Python because Python does not have pointers.

However, it would be possible to write a scan(string,format) function that
would return a tuple of values.  Since Python uses C formats for the %
operator, it would add a nice symmetry.  [IE, scan(format%tuple,format) ==
tuple].

It might be possible to do this by replacing the %format specifiers by the
corresponding re specifiers and using re behind the scenes.  Or by using
openly available scanf code.
