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: env_windows.go
    path of file: ./repos/podman/pkg/env
    
    the code of the file until where you have to start completion: package env

// ParseSlice parses the specified slice and transforms it into an environment
// map.
func ParseSlice(s []string) (map[string]string, error
    
func ParseSlice(s []string) (map[string]string, error) {
	env := make(map[string]string, len(s))
	for _, e := range s {
		if len(e) > 0 && e[0] == '=' {
			// The legacy Windows CMD command interpreter uses a hack, where to emulate
			// DOS semantics, it uses an illegal (by windows definition) env name for
			// state storage to avoid conflicting with user defined env names. This is
			// used to preserve drive letter paths. E.g., typing c: from another drive
			// will remember the last CWD because CMD stores it in an env named "=C:".
			// Since these are illegal, they are filtered from standard user access but
			// are still available in the underlying win32 API calls. Since they have
			// zero value to a container, we filter as well.
			continue
		}

		if err := parseEnv(env, e); err != nil {
			return nil, err
		}
	}
	return env, nil
}
