Re: [go-nuts] New identifiers and selectors in short variable declarations

It is not a new declaration, it is definitely an assignment. This can be determined because (in Go) a new declaration has effects when closing over variables: https://play.golang.org/p/a_IZdOWeqYf (ignore the obvious race condition; it works the same but looks uglier with the requisite locks:

Re: [go-nuts] New identifiers and selectors in short variable declarations

This works: b, a := 1, struct{ x int }{2} But this doesn’t: var a struct{ x int } b, a.x := Returns1And2() But this does: var a struct{ x int } var b int b, a.x = Returns1And2() And this does: var a int b, a := Returns1And2() Matt On Tuesday, January 9, 2018 at 5:59:49 PM UTC-6, Kevin
