thanks Alex for your response . I tried it ... It compiled fine .. but the double dispatch does not seem to work correctly ..
It some how reverses the arguments and then dispatches to the correct function for the reversed arguments and the function works properly .. i.e. when I do (- (Complex. 1 3) 3) .. I would expect (Complex. -2 3) but I get (Complex. 2 -3) which is what I would expect to get when I do (- 3 (Complex. 1 3)) . I am trying to make it work right .. but I thought some of you may better able to fix it. Thanks, Sunil I am trying to debug it .. but would like some I am still trying to understand the code and figure it out..
