I’ve started a separate thread, [How to learn language extensions](http://discourse.haskell.org/t/how-to-learn-language-extensions/7252), for those who’ve “tuned out” this thread.

> Specifically the docos on `FlexibleContexts` hasn’t got much terser AFAICT. Are you perhaps confusing with [`FlexibleInstances`](https://downloads.haskell.org/ghc/latest/docs/users_guide/exts/instances.html?highlight=flexible#relaxed-rules-for-the-instance-head)? Which is indeed chunky, and rightfully so. I’da thought any project that uses one would use both.

My link to the [latest docs for FlexibleContexts](https://downloads.haskell.org/ghc/latest/docs/users_guide/exts/flexible_contexts.html) was indeed correct and nothing to do with FlexibleInstances. Shall we continue in the other thread?
