I don't know how much you understand my above question,which is s= o
valid.

From the doc: http://www.ruby-doc.org/core-2.0/Fixnum.html

Clearly mentioned that - ***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.**

The same I agreed for Bignum,FLoat and Symbol.

Now the `true`,`false` and `nil` also has fixed Object_id, But why they
are allowed to have singleton class on them. -- This is my curiosity to
know and I think which is to legitimate.

Thanks.
