Absolutely.  For one thing, I could see this playing a role in the
eventual, elusive, possible on-line snippet collection/garden/clinic.

With that in mind, one enhancement might be to have a way to display
the code and the output at the same time -- say, an <rbi_code_show>
element, such that this wiki input:

   Here's my code and output:
   <rbi_code_show>
   def thing
     puts "hi"
   end
   thing
   </rbi_code_show>

would result in:

   Here's my code and output:
 
   code:
     def thing
       puts "hi"
     end

   output:
     hi

In this scenario, the code would be executed once (when the page was
saved) and the results stored as text.

This could be handy for automatically generating benchmarks during
a discussion of a code snippet, and such things.
