Quick theoretical question:

I have code which is parsing a GraphQL query into its AST, and then transforming that into a more specific "AST" (really just nested Kotlin dataclasses)
Would this be something that lenses would be beneficial to for performance purposes, rather than creating an entire new AST object?

In terms of performance it will be equal to copy that is on data class but it has more functionality since it can also work over collections, sealed types etv

Ah got it -- thank you!
