Right now, everything is in one file, perf_query.g4. Further, some productions (expressions and predicates) are shared across the imperative and declarative parts. This results in quirky expression and predicate productions that take either a state variable or a column name at their "leaf/terminal" nodes because either can be used within the imperative aggregation functions.
