Looks a lot like the already proposed check/handle keywords that was met with a lot of push back from the Go community:

Doesn't look like the proposal adds anything new.

This new proposal is explicitly a simplification of the previous check/handle proposal. And for the record, there was a lot push back, but also a lot of support for the check/handle proposal. Language design is an iterative process.

It is from a core team member, usually those proposals tend to win in the end, as already occurred a couple of times.
