gofmt gives an "expected identifier" warning about this function signature at this point:
func foo() (*int, y int) {}
^
However, it does not complain about this signature:
func foo() (int, y int) {}
How can I name one return value without having gofmt complain about the unnamed pointer return value?

The Go Programming Language Specification
The blank identifier is represented by the underscore character _. It serves as an anonymous placeholder instead of a regular (non-blank) identifier and has special meaning in declarations, as an operand, and in assignments.
Use the blank identifier (_). For example,
package main
func foo() (_ *int, y int) { return nil, 0 }
func main() {}
