I missed that, interesting!

There's still something more that can be improved, actually we 
have that at CT:

```
src/ops/sql/semantics.d(521,19): Error: uncaught CTFE exception 
`object.Exception("role analysis_operator can't select table 
aois. SQL: select count(leg_id) from aois where leg_id = $1 and 
snapshot_id = $2 and aoi_id = $3")`
```
