Subject: Re: Bignum-Fixnum-Numeric confusion

From the doc: http://ruby-doc.org/core-1.9.3/Fixnum.html

I found the below features :

Fixnum:

(a) Fixnum objects have immediate value. This means that when they are 
assigned or passed as parameters, the actual object is passed, rather 
than a reference to that object. - Can the same be shown in IRB. Hope 
then only it will be correctly understood by me.

(b) Assignment does not alias Fixnum objects. - What does it actually 
then?

(c) "There is effectively only one Fixnum object instance for any given 
integer value, so, for example, you cannot add a singleton method to a 
`Fixnum`." - Couldn't understand the reason of not to add the 
`singleton` method with Fixnum object instances.

-- the above (b) and (c) points are also made me confused.
