TypeScript already has such type operators though. For example: type T = keyof { a: null, b: null } Here T is “a”|”b”, no automatic semicolon is inserted after `keyof`. While I don’t personally write code like this, I’m sure that someone does. It’s perfectly within the rules, after all. While it’s true that TS doesn’t have to follow JS rules for semicolon insertion in type expressions, it always has done, and probably always should do.
