I'm a bit confused. Your subject line IS handled by this code. Indeed,  
this is what I grabbed from some of my code when I read the subject  
line:

   def explore
     Object.const_set :"G", self
     require 'irb'
     puts "Your grammar is in the constant G"
     IRB.start(__FILE__)
   end

So, what is the actual subject of this question? It doesn't seem to be  
"long-windedness" (below) either.

I'm confused and havet o assume the question is a bit vague. How is  
"$c = " long winded? What do you actually want to know?
