Description

These are a bunch of simplifications related to field access that can be interesting to support.

DONE

{ unrelated = 1, field = someFn value }.field
--> (someFn value)

{ a | field = someFn value }.field
--> (someFn value)

{ a | unrelated = someFn value }.field
--> a.field

(\a -> { field = a }) >> .field
--> identity

/DONE

More complex:

value |> (\a -> { field = a }) |> .field
--> value
