Trading in Futures
summary
Covers concrete Scala 2.12 changes and practical demos: deprecation of onSuccess/onFailure, new Future.flatten to avoid identity allocation, a transformWith/transform trio that enables composing try-to-try and try-to-future logic and powers root compression, added Future.unit and a nonleaking Future.never, and blockContext/blocking hooks plus ExecutionContext shown as a pluggable interpreter. A live demo builds a manual ExecutionContext queue that initially fails until the queue is drained, proving the interpreter model, and notes ForkJoinPool common pool naming and tuning.
