I was actually wondering (in Zig, which has a per-statement "try" which is essentially the same as the ? in Rust) whether it also makes sense for whole blocks, which would look a lot like traditional try-catch block in languages with exceptions, e.g. instead of:

    try may_fail_1();
    try may_fail_2();
    try may_fail_3();

...this could be grouped into:

    try {
        may_fail_1();
        may_fail_2();
        may_fail_3();
    } 

...but would behave exactly the same as the indiviual trys, if any function in the block returns with an error, that same error is passed up to the caller. But I guess that forcing individual trys makes you think harder about handling individual errors than just pushing the responsibility for error handling up the callstack.
