on a sidenote, I've been playing with:

def swapper(obj,a,b)
 obj.instance_eval("#{a},#{b}=#{b},#{a}")
end

swapper(self,:a,:b)


but this does'nt work.

Anyway, if I do this:

p a
p b

 self.instance_eval("#{:a},#{:b}=#{:b},#{:a}")
p a
p b

it works as expected (i.e. swaps the variables)

Some hints to explain me this ?
