Hello
It seems that this code <https://play.golang.org/p/C5jbcieUS6> doesn't
compile :
func main() {
var err error
err = f()
}
*prog.go:8: err declared and not used*
but this one <https://play.golang.org/p/Y5zc4sLbtE> does :
func main() {
var err error
g := func() {
err = f()
}
g()
}
Is the function binding regarded as a "use"? Or does escape analysis
decide to not check too deep about never-read variables?
Whether expected or not, I supposed this compiler behavior won't change,
because of the Go1 compatibility promise.
Cheers
Val
