+1 for more 'return self' at the end of methods which currently don't
return anything (well, we get the default None), as long as it's
sensible.  I really like this 'message chaining' style of programming,
and it annoys me that much of the python stdlib gratuitously prevents
it by NOT returning self in places where it would be a perfectly
sensible thing to do.

I find it much cleaner to write

x = foo.bar().baz(param).frob()

than

foo.bar()
foo.baz(param)
x = foo.frob()

but perhaps others disagree.

Cheers,

f
