I'm looking to make domains proper types and eliminate the need for
special domain checking in the case where it is not a check constraint
check. I'm trying to influence a more logical implementation of
domains that removes some code and gains us features. Also it
should eliminate some (all?) of the current limitations with regards
to using domains as subtypes. It will also pave the way for
implementation of create type under type.
