> Why would you want to detect this?

There's any number of reasons. When I give them, the typical response is, "don't do that" - ie, determinine if a function will throw on [[Call]], or to help determine `IsConstructor` in an engine that doesn't support `new.target`. I've also written modules that detect if something's an arrow function, or a generator, etc - it's a use case that exists. Sadly, it's impossible without this fix.
