--------------------------------
[~sershe]: LGTM - +1.
I'll make a note & do a bit of type refactoring after talking to [~hagleitn]

> {code}
> select count(1) from accounts a, transactions t where year(a.dt) = year(t.dt)
> and account_id = 22;
> $hdt$_0:$hdt$_1:a
> TableScan (TS_2)
> alias: a
> filterExpr: (((account_id = 22) and year(dt) is not null) and (year(dt))
> IN (RS[6])) (type: boolean)
> {code}
> Ends up being evaluated as {{year(cast(dt as int))}} because the pruner only
> checks for final type, not the column type.
