Gordian concatenation recursion. I am so excited to see this working!

gordian recursion

def concat(x, i)

    def _concat(j, w, e)
        if(e > 0)
            return _concat(j + w, w, e - 1)
        else
            return j
        end
    end
    
    return _concat("",x,i)
end
 
 
print(concat("Hello World", 3))
