Conceptualizing Large Software Systems
summary
Claims a concrete toolchain: use Go cover to mark exercised lines, prune everything else, then run compiler-style simplifications to produce a stripped-down code that reveals the core behavior. Prototype runs against real code (net/http) and yields a readable net HTTP dialConn implementation that shows persistent connection setup and goroutine IO. Adding a second test (HEAD) injects surprising differences — content-length handling and object-pool reinitialization — so the tool both works and exposes where incidental complexity hides.
