Ok, I'm confused. You seem to be saying that first and last are different than
using [] because they are methods and return a value, right? Does that mean
that you mean to imply that Array#[] is not a method or that it doesn't return
a value?
I'm asking because it is starting to look to me like that is what you're 
saying, but Array#[] most certainly is a method and it most certainly does 
return a value.
