@marmbrus I've pushed it to
https://github.com/willb/spark/tree/spark-2226-broken -- if I split out the
`UnresolvedHavingClauseAttributes` to a separate batch and add a
`ResolveReferences` (as in willb@16b3dfc), things seem to work, but if I put
`UnresolvedHavingClauseAttributes` in Resolution (as in willb@76ae5c1), things
fail with
No function to evaluate expression. type: AttributeReference
I'm sure I'm missing something simple here. Thanks for taking a look!
