I noticed 2.7 was released without any official pattern matching documentation, other than the link to the (outdated) presentation.

I don't know, maybe this work is already in progress internally, or maybe it consciously left this way, but I'd like it to be fixed for wider feature adoption.

In this PR, I am trying to document PM to the best of my understanding: https://github.com/ruby/ruby/pull/2786.

Can be closed, as PR is merged :)
