Library Reference : ri :: Language Reference :?

ri is cool -- library reference at your fingertips (literally ;))

Is there a gem that helps me do something similar with language
reference with syntax and an example or two? For instance,

$ rubyi
-> case
--> multiway decision control structure
--> example: tax = case income
                    when ... then ...
                    when ... then ...
                    else
                  end

-> rescue
... etc.

Regards,
Kedar
