You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: positive_tests.go
    path of file: ./repos/go-critic/checkers/testdata/builtinShadow
    
    the code of the file until where you have to start completion: package checker_test

/*! shadowing of predeclared identifier: len */
/*! shadowing of predeclared identifier: cap */
/*! shadowing of predeclared identifier: complex64 */
func warnParams(len int, cap string) (complex64 complex128) {
	return 0
}

type shadower struct{}

/*! shadowing of predeclared identifier: bool */
func (bool shadower) shadowThem() {}

func genDeclShadow() {
	/*! shadowing of predeclared identifier: byte */
	var byte = 1
	var
    
func genDeclShadow() {
	/*! shadowing of predeclared identifier: byte */
	var byte = 1
	var (
		/*! shadowing of predeclared identifier: true */
		true = false
		/*! shadowing of predeclared identifier: false */
		false = 10
	)
	/*! shadowing of predeclared identifier: error */
	const error = "error"
	const (

		float32 = 32

		float64 = 64
	)

	_ = byte
	_ = true
	_ = false
