Re: How do I pass an operator as proc parameter?

I think you need to use a Template or an anonymous function to do what you want:
    
    
    template testA[T](a: T, action: untyped, b: T): T = action(a,b)
    echo testA(1, `xor`, 2)
    
    proc testB[T](a: T, action: proc(a,b: T):T , b: T): T = action(a,b)
    echo testB(1, proc(a, b: int): int =  a xor b, 2)
