Iterator Haiku

by Casey Carter

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Recently proposed changes to the ranges TS distill its seven iterator categories back to five without sacrificing any expressive power. Removing operations that are extraneous in the Sentinel world eliminates a potential source of programming errors.
