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: metadata.go
    path of file: ./repos/mgmt/lang/interfaces
    
    the code of the file until where you have to start completion: // Mgmt

func DefaultMetadata() *Metadata {
	return &Metadata{ // the defaults
		Main: MainFilename, // main.mcl
		// This MUST be empty for a top-level default, because if it's
		// not, then an undefined Path dir at a lower level won't search
		// upwards to find a suitable path, and we'll nest forever...
		//Path: PathDirectory, // do NOT set this!
		Files: FilesDirectory, // files/
		//License: "", // TODO: ???

		bug395: true, // workaround, lol
