Hi,

Your descriptions are correct, but I find your terminology a bit 
strange. For example, you describe "result = []" as "opening an empty 
array namend result". I'd rather call it "create an empty array and 
assign it to the variable 'result'". Because "result" isn't the name of 
this specific array (that's what you'd use a constant for), it's a 
generic reference which may point to any object at any time.

By the way, the "transmogrify" method is actually a reimplementation of 
Enumerable#map:

http://ruby-doc.org/core-1.9.3/Enumerable.html#method-i-map

Except that it forces you to pass a block (whereas Enumerable#map will 
return an Enumerator if you don't).
