Ordering attributes for dynamically generated class

[David Pratt]

Hi list. I use 'type' to generate classes but have a need to order  
the attributes for the generated class. Of course a dict is not going  
to maintain ordering. Is there any way to dynamically generate a  
class with attributes in specific order?

my_new_class = type( 'MyNewClass', tuple_of_bases, dict_of_attributes)

Many thanks,
David
