Thread:Talk:Requests for comment/Isolate custom jQuery libraries/Underscore.js

This might be a little out of scope for the RFC, so I'm commenting here instead of inline. You mention Underscore.js in a few places – has anybody considered including it in core, preferably as a default library like jQuery? Because I'm getting really tired of not having a sane consistent set of functions for "advanced" features like whitespace trimming, regex escaping or a sane map function :)
