# [derive(Clone)] Is Broken

Derive Clone is not broken. It is basic. I’d say this is a good area for a dependency but not the core Rust functionality. Keep derive simple and stupid, so people can learn they can derive stuff themselves. It also avoids any surprises.

I disagree. I think the current behaviour is surprising. The first time I ran into this problem, I spent half an hour trying to figure out what was wrong with my code - before eventually realising its a known problem in the language. What a waste of time.

The language & compiler should be unsurprising. If you have language feature A, and language feature B, if you combine them you should get A+B in the most obvious way. There shouldn't be weird extra constraints & gotchas that you trip over.
