releasing its resources (in reverse order of acquisition).
Example:
val lines = Using.Manager { use => use(new BufferedReader(new FileReader("file.txt"))).lines() }
If using resources which require an implicit Manager as a parameter,

parameter:
Example:
val lines = Using.Manager { implicit use => new SafeFileReader("file.txt").lines() }
