Switching higher-order streams to first-order streams

<!-- SC_OFF -->I discuss streams. It's a pretext to learn about higher-order streams, like flatten and to introduce a new stream: switch! It's very useful, and will have no secret for you. <!-- SC_ON --> submitted by /u/Hywan (https://www.reddit.com/user/Hywan)

VOMPECCC: A Modular Completion Framework for Emacs
https://www.reddit.com/r/programming/comments/1sn4e7z/vompeccc_a_modular_completion_framework_for_emacs/

<!-- SC_OFF -->"I'm writing this post because these packages have recently taken the Emacs community by storm, but I rarely see discussions on how they relate or how they compose together to provide a feature complete ICR system in emacs. These packages implement concretely what the antecedent post argues in the abstract: completion is a substrate, or set of primitives, on top of which users can build rich interfaces for effortlessly interacting with your machine to do almost anything." <!-- SC_ON --> submitted by /u/misterchiply (https://www.reddit.com/user/misterchiply)
