Ok, we won't call them exception handlers. Instead, call them "if anything goes wrong in this function do this" handlers.

Those are very different things, whatever you want to call them. check/handle doesn't involve unwinding the stack, and doesn't default to crashing your program if you forget to add a handle block.

Is that a good thing?

Yes, because instead your program won’t compile if you forget to handle an error ( except in the case of a function which only returns error, which you can ignore by mistake - I would like to see that fixed in go 2 as well).
Expect to see a lot of `_, _ = fmt.Println(...)`, then.
