Hello,
This has flummoxed me quite a bit in using ri for finding method docs.
Why doesn't this work?
ri Hash#map
(ruby 1.8.2, ruby 1.9.0 (2005-01-09))
RDoc should have all the required info it needs to walk up the ancestors, since it knows the superclass of the class, and the modules mixed in. So when there isn't a hit, it should go up in the hierarchy instead of saying "Nothing known about Hash#map" and giving up.
A little persistence, that is all I ask.
