Iterator Haiku

by Casey Carter

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Iterator Haiku: How five iterator categories blossomed into seven, and Sentinels trimmed them back to five again. 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.
