This is a very clear statement of the problem -- browsing the spec to
figure out what X is about in JS is a bad idea.  But that is as it
should be. The spec formally defines the language; it is not for
browsing to learn about the language.  If you want to learn what a new
feature like `super` does, you'll want to read blog posts and
examples, until it appears in tutorials on the web, and then it will
appear in future versions of Dave Herman's or David Flanagan's or Doug
Crockford's books, if they decide to write them.

If you ask the spec to serve two masters, then it will do one badly.
In the Scheme community, the existence of a spec that many people find
to be a good introduction to learning the language has been actively
bad for the future development of the language.
