which suggests that you're really looking for a different constructor
as a class method.
Yes!
Will revise the patch accordingly
and use Just's suggested name, fromseq().
Do you prefer the default value to be None or True?
Earlier discussions on python-dev showed that
True is more meaningful to some in the context of
membership testing.  OTOH, dict.setvalue and
dict.get both use None.
I think it should be None -- let's be explicit when we want True.
And maybe the method should be named fromkeyseq, because there
is another constructor that creates the dict from a sequence
of items. (Maybe this constructor should be made into a
class method fromitemseq?)
