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
