Here’s another that kills me every time, I want to compose where I know types are mismatched and I am okay with a runtime fault downstrean. This is hugely powerful to move very fast in, eg, REPL-driven development environment where you build and verify pieces of code incrementally. Not being able to do this is a enormous productivity killer, relative to say a dynamic/Clojure.
