I am not sure what you are saying. Every (C) int is checked to see if it is in the preallocated range before making a new Python int object. The reason for the low limit is the various time-space tradeoffs applied across the entire range of programs. Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list
