Maybe... it's still more verbose for no gain as I see it. 

I think the default implicit chaining is correct in the default case. It's 
only if you want to adjust that (or suppress is with `from None`) that the 
extra clause comes in handy. I think using the default unless there's a 
reason not to is, in general, a good policy. 

I know I'm -1 on this particular change, for the reasons in this thread, 
but thank you for your efforts nonetheless. :)

Kind Regards,

Carlton
