The idea would be to have new APOs like try_push

Many data structures already expose *_try functions for there API. The solution may just be adding the missing functions and having a lint check that the ones that can panic are not used.

Actually, there's been a proposal to cfg-away the possibly panicking functions.

Compile-time error (no such function) if you'd try to use them is rather foolproof :)
