Well. I wasn't aware of the fact that other packages use these 
constructors. Please let me know if you think additional BBB support is

AFAICS it's fine to use the ``type`` constructor instead of 
``makeClass`` in Zope 2.13.

``SimpleViewClass`` is not available in Zope 2.13, so that part will not 
work in Zope 2.13. ``makeClassForTemplate`` has a slightly different 
signature, but the way five.formlib uses it should work with both 
versions. So I would fall back to ``makeClassForTemplate`` if import of 
``SimpleViewClass`` doesn't work.
