File be/src/exprs/expr.h:

Line 159:   virtual BooleanVal GetBooleanVal(ExprContext* context, const TupleRow*);
> i wrote that comment before i reacquainted myself with the approach to spec
I don't see it conflicting with the abstractions: Expr stores static data which can be _shared_
among fragment instances while the latter two have to be created per fragment instance for
execution. These interfaces don't modify the states of an Expr.
