Class ResultVariableDecl
A result variable declaration.
Examples:
int
string
error
r io.Reader
output string
err error
x, y int
as in the following code:
func f1() int { return 0 }
func f2(input string) (string, error) { return "", nil }
func f3(a int) (r io.Reader) { return nil }
func f4(input string) (output string, err error) { return}
func f5(e error) (x, y int) { return }
Note: x, y int is a single ResultVariableDecl even though it declares
two different result variables. Use the member predicate getTypeExpr() to
get int, getNameExpr(0) to get x and getNameExpr(1) to get y.
