I'm not too keen on adding a section like this to the itertools docs.

Instead, I would be open adding "further reading" section with external links 
to interesting iterator writeups in blogs, cookbooks, stack overflow answers, wikis, etc.

If one of you wants to craft an elegant blog post on "Grouping, Blocking, or
Chunking Sequences and Iterables", I would be happy to link to it.
