Review Comment:
Keeping state in `InheritableMetadata` doesn't work because it is reused
each time the reader produces an iterator. That causes incorrect row ID
assignment (caught by the tests I'm working on). Instead, I've introduced this
assigner function that is called where `InheritableMetadata` is used.
`InheritableMetadata` is used for constants, this is used for state-based ID
assignment.
