Hi-

I mean no disrespect, but the online version of the PP book doesn't
list the hierarchy ("figure not available").  Ought one be required to
purchase a commercial text to obtain the exception classes in the ruby
language?  This seems like information that ought to be freely
available- requiring dead-tree reference material to learn something
this basic about the language will discourage it's popularity, and
ultimately, the sale of ruby texts.
