What is the output from % ruby -v

I know partly what is happening is making the keys for a hash as 
symbols, hence symbolize_keys.  Now that may have been obvious, but is 
the reason why?  Turns out, at least for me it was not obvious that a 
String key and a symbol key of the same name are not equivalent, that is 
they don't hash equally.  So, I believe this is part of the equation, 
wish I knew more.  Hope this leads to getting help.
