Thanks, I will be using this whereever there are classes, but would like 
to know, is there any way i can do it with methods. I know i could 
define the hash as a global (or maybe module level object) but that 
would not be a clean solution.

There is also one question I would like to ask as a ruby newbie 
(struggling to grow up). Is the above approach of passing blocks to an 
ask method making it more "rubyish" or better than returning the input 
character and letting the user decide what to do.
