Coolness, or ugliness?
In Ruby many operators are implemented as method calls. For example you can write:
>> 3 + 4
=> 7
as:
>> 3.+4
=> 7
In this case we call the method + on the Fixnum 3 and pass as argument the Fixnum 4.
>> 3.class
=> Fixnum
While it's good to have expressions built-in as methods, so the programmer can extend/modify them I think thay still relying on the receiver class to determine the method to be called is not the best solution. Personally I think that generic functions, found for example in Lisp, are a way better and more elegant solution
