How does an Integer whose base is 10 differ from an Integer whose base is 
something else? Or how do you know what base an Integer has?
Is 0xA a decimal number? No? So you'd probably say that 0xA is an Integer in 
base 16 and 10 is an Integer in base 10, right? But 0xA and 10 are the same 
object. 0xA.object_id == 10.object_id #=> true. How can that be if the base 
is something inherent to the Integer (answer: it isn't).

Integers don't have a base. Only string representations of Integers do.
