Ruby does not have an increment operator (++). It does have #succ but  
that is not in place.

as far as your increment goes:

% cat increment.rb
class Fixnum
   def increment
     self = self + 1
   end
end

a = 1
a.increment


% ruby increment.rb
-:13: Can't change the value of self
     self = self + 1
