I think I'd prefer that in try_job_base.py.

Causes a circular dependency base-> bb7 -> base
and bb8


As well as the implementation of a language for describing a set of
modifications being separable from a try job.

No because since it's a mixin, you can just call the superclass member;

self.parse_decoration(foo)

so no it's not a "circular" dependency. See how self.last_good_urls is used in
the mixins.
