I'm unsure of what you mean; if you explain why this doesn't solve
your problem, we'll go from there?:

I suspect you want something that can be used in the following way:
     obj = dstruct(...)
     ...
     obj.pack(5,4,3,2)

To put a little meat in, I'll have pack simply print its args:

class dstruct(object):
     ...
     def pack(self, *args):
         for element in args:
             print element

This works, now what is unlike what you want?
