   These test failures are legimate.  I hacked at this a little today and it quickly started to get out of control :laughing: 
   
   The basic issue is that I am transferring to a model where all expressions (projections, filters, guarantees) get normalized as we start to work with them.  This allows us to cleanly handle duplicate column names and similar issues.  Unfortunately, it's exposing a number of places in the current datasets code where we are explicitly relying on named refs and I am needing to work around that.
