Usually when you import the standard functions, it is because you are using the function oriented, not the object oriented style. With the latter, you don't need to import :standard.
I'm unclear about what you mean by "use multiple parameters".
You can get the values of any parameter names using param('name'), and you can get all the names returned as a list if you wish by using param().
