The field_spec is an ordered dictionary of field_name : FieldClass
pairs.  So field_spec.keys() would get you a list of field names.

You might have to provide a more detailed use-case.  We do quite a lot
of reflection in our apps and haven't had a need for what you describe
yet.  So either we've already got ways of getting what you want that
aren't immediately obvious, or we have baggage that we are used to
carrying around and things need to be made easier.  At this point I'm
not sure which is the case.
