Yup, it was supposed to read `to_sym.to_s'

It may just be my own preference, but I think it's nice to restrict the 
`types' of arguments a method can take -- not by class, but by defined 
methods. So when you say that #get_const takes a symbol as an argument, 
you know you can give it every object that responds to #to_sym.

But yes, #to_s could be used.
