shouldn't this method be renamed to visitFieldDereference ?
It only applies to expressions of Row type
It's a fixed compile-time value, so it's unnecessary to represent it as an arbitrary Expression. That's a vestige from when it used to be named Subscript and represented array accesses, too.

Rename to FieldReference and make the field an integer instead of an IR expression.
This node is only relevant for expression of Row type, and the field is known at construction time.
