Summary

0007326: #sum and #average do not work properly with empty collections

Description

Sending #sum or #average to an empty collection will yield an "attempt to index non-existent element..." error. #sum and #average should check first to see if the collection is empty and then, if it is, either return zero (my preferred behavior) or raise a more appropriate error.
