> This will be necessary for ARROW-11928 since some ExecNodes will be
> constructed with one or more Expressions. For example FilterNodes will
> evaluate an Expression against their input batches to produce selection
> vectors.
> This should probably include factoring out dataset-specific considerations
> such as allowing input batches diverge slightly in schema. Bound Expressions
> should refer to their parameters by index so that by-name lookup can be
> avoided.
