Deprecated as of Tcl 8.5
A tcllib package which handles arbitrary-length integers. Possibly deprecated with Tcl 8.5, in which [[expr] provides large integer support.
LV I wonder whether there would be some possibility of adding a Tcl 8.5 version of this package that just makes use of expr's functionality. That way applications using the package need only have the new tcllib to work, rather than have to be recoded.
AK: IMHO such a compatibility layer would be a good thing.
