# hmmmm.... can we really just arbitrarily clobber this?
# wouldn't that be surprising to calling code that passes in a record/model?
# One use-case of this seems to be to reduce the amount of possible errors a command reports
# by declaring that only some subset or none of the attributes are mutable.
# However, we shouldn't react to this by clobbering the mutable state of the record because it might not
# be a fresh record fetched from a primary key it might be an already loaded record/model from some other
# context and that context might be surprised to learn that we've clobbered its mutability status.
# Solutions?
# 1. In the case of models, we could duplicate the model if the mutable value is different.
# 2. But what about entities? We almost need some sort of proxy entity that tightens the mutability?
