Is there any facility to do computed fields (similar to Archetypes) in
zope.schema fields and z3c.form?

I want to apply some kind of function (sum, average, etc) callable across
other fields' respective values on the same form/context -- e.g. computed
field_d = SUM(field_a, field_b, field_c).

My only current constraint is that it be plone.supermodel-friendly
(possible to serialize; maybe something syntactically similar to the way
spreadsheets handle expressions).

My sense is that there is not anything yet out there to do this?

Thoughts?
