Denis Defreyne wants to give this talk

Clean & fast code with enumerators

Ruby’s Enumerator class is a powerful tool for writing code for dealing with streams of data and events, while being easy-to-understand and at the same time both concurrent and parallel.

This talk will go in more detail on how to do so, and also show [SlowEnumeratorTools](, which provides some of the glue code that makes Enumerator nicer to use, and faster to boot.

There will be some overlap with Sergio’s “Understanding Unix pipes with Ruby” talk from the November meetup.
