 We propose following sytax for Using Directives (within special comments described above):
 
 ```
-UsingDirective ::= "using" (Setting | Settings)
-Settings ::= "{" Setting { ";" Setting } [";"] "}"
-Setting ::= Ident [Values | Settings]
-Ident ::= ScalaIdent { “.” ScalaIdent }
-Values ::= Value { "," Value} [","]

 - String literals and numeric literals are similar to Scala.
 - No value after the identifier is treated as true value: `using scalaSettings.fatalWarnings`
 - Specifying a setting with the same path more than once and specifying the same setting with a list of values are equivalent
-- A path created using dot-separated idents is semantically equivalent to a path created by nesting idents:
