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: target.go
    path of file: ./repos/mage/target
    
    the code of the file until where you have to start completion: package target

import (
	"os"
)

// Path first expands environment variables like $FOO or ${FOO}, and then
// reports if any of the sources have been modified 
    
func Glob(dst string, globs ...string) (bool, error) {
	stat, err := os.Stat(os.ExpandEnv(dst))
	if os.IsNotExist(err) {
		return true, nil
	}
	if err != nil {
		return false, err
	}
	return GlobNewer(stat.ModTime(), globs...)
}
