The usual response to this kind of thing among gophers is "don't do that", which is a reasonable response given that if the language designers thought Go should have try/catch/finally they'd have included them in the language.

As it is, they decided against it. Some may disagree with that, but the entire rationale is public and based on pragmatism. Go is a fairly opinionated language, so if you disagree strongly with those choices, you probably ought to pick another language. Part of the beauty and value of Go is that all Go code tends to read like all other Go code. Obfuscation and unnecessary abstraction are frowned upon.

In this case you can get much the same result with local functions and defer (which you are creating here anyway). There's little value in wrapping it up with this syntax other than to make your Go code less idiomatic.
