My bad. I was using throw when I thought I was using raise.
Subversion has the right code now, and I'll upload the 0.9.1
gem shortly. Apparently I hadn't tested that path.

With regard to typed_attr, there are still ways to violate the
constraints: use a default value that isn't allowed (or not
use one where nil isn't allowed), or directly assign to the
member variable from a member function. There's no good way of
avoiding that really though...
