What version of Go are you using?

go version go1.13beta1 windows/amd64

Does this issue reproduce with the latest release?

yes

What did you do?

package main

func main() {
	_ = func() string {}
}
gofmt -r 'a->a' -d funcreturn.go

What did you expect to see?

The return type of the function literal is still string, without parentheses.

What did you see instead?

The return type is enclosed in parentheses.

-       _ = func() string {}
+       _ = func() (string) {}
