    #@wraps(func)
    def new_func(*args):
        num,given=minpara(func,args)
        #print num,given
        if (num,given)==(0,0):
            return func(*args)
        else:
            return curried(functools.partial(func,*args))
    return new_func
@curried
def sun_1(a,b,c):
    return a+b+c
@curried
def sun_2(a,b,c):
     return a*b*c
if __name__=="__main__":
    print sun_2(1,)(2)(44)
    print sun_1(1,)(2)(44)
    print sun_2(1,2)(23)
