As for syntax; what about coopting/integrating with the function 
annotation syntax?

so:

def func(args: list, kwargs: attrdict)
and correspondingly in the function call?

a, b:tuple = someiterable?

I guess a rule that interprets every function argument annotated as a 
subclass of list or dict as a special case would severely restrict its 
intended use though...
