I think this is a great idea, and a huge improvement over
In addition to the discriminated union, it would also be nice to
change this to use a StmtVisitor if possible, just to simplify the
code and make it more modular. It would be natural to move the
implementation to its own file if it is large, even though the
entrypoint would stay a method on Expr.
