I may have a crush on the TypeScript compiler, because of stuff like this
You may be interested also in checking out the implementation of Lens in monocle-ts, one of the libraries in the fp-ts ecosystem

Haskell Lens Tutorial by Exercises
For anyone - anyone who's faffed around with JavaScript's spread syntax when working with nested immutable data, anyway - struggling to understand the general concept or utility of lenses, I'd encourage looking into monocle-ts. The motivation [0] that kicks off the README instantly made me a believer, and TypeScript's idiosyncratic type system makes using the library remarkably natural; it fits right in without needing to deal with anything analogous to Template Haskell.

Is there a cleaner way to immutably update a deeply nested attribute? (I feel like this is not very clean)
You could have a look at the monocle-ts library. It was designed to deal with this kind of problem.
