The Value in Trees
summary
Large gigabyte document trees cause crashes, corrupt saves and fragile undo; the claim is that modelling everything as value trees (structs/enums) plus immutable snapshots fixes those: snapshots share unchanged subtrees so edits only copy a path to the root, enabling stable undo and safe concurrent rendering. This is proven by a Sketch refactor and a new Swift editor prototype; an experimental repo called Impeller implements git‑style syncing for structs (six weeks of work, not yet production).
