This is a very ambitious goal I'm not sure I share completely. Taking for example the documentation for `Hash`, one would need to talk about covariance of methods returning a hash (i.e. `Class.new(Hash).new.select{}.class` vs `Class.new(Hash).new.merge({}).class`), of treatment of a key `Float::NAN` (which is not `eql?` to itself), of recursive hashes, of the arity of enumerators (see https://bugs.ruby-lang.org/issues/14015#note-8 ), of the performance of hash lookup / insertion...
All these details can not be repeated for each method, the same way we can't quote in full the floating point standard for `Float#+` and repeat it for `Float#-`, etc. On that subject, an example with `0.1 + 0.2` might be helpful though.

I have misgivings:
* Some of this material is very old, like the text and example for user-defined hash keys.
* Some material I consolidated from earlier doc for individual methods, which now link to the relevant sections.
* All is factual, and not repeated elsewhere in the page.
My view has been this: This is API reference documentation. Ruby/ruby should have *the reference documentation*, and therefore should omit nothing.
If material such as this is to be included, I see three possibilities:
* Include in-line, as now.
* Link to on-page 'footnote', with Back link.
* Link to off-page rdoc, likely in doc/ dir.
I'd love to hear some opinions on this.
