+1 without a doubt. I wonder whether we still need all the other fields and 
should just use collection. Certainly I would do that in my 3rd party code. I 
would prefer 

numbers = Collection(
    title=u"Numbers",
    unique=True,
    ordered=True)

be much nicer than

numbers = List(
    title=u"Numbers",
    unique=True)

since it is much more explicit and I do not have to remember the rules for 
what a set or a list is. Also, notice that at least 70% of the time where we 
use a List/Sequence now, it could be also a set. Usually we do not care about 
order.

Regards,
Stephan
