Subject: how to call operator as function

Hi *,

 could you help me please ? I'm trying to write a code where I could have
operators' functions as values of hash and executing them in way like this 
(formal code):

#=============================
operators = { "+" => Fixnum.+, 
              "-" => Fixnum.-, 
              "++" => Myclass.++}

op = "+"

result = operators[op](left,right)  if left.class==Fixnum and right.class==Fixnum
#============================

is it possible ? Thanks,

Cheers,

 V.
