class ArrayLiteral : Rubinius AST ArrayLiteral {
    def initialize: @array line: line { 
      @array nil? if_true: { @array = [] }
      initialize(line, @array) 
    }
    def bytecode: g { bytecode(g) }
}

As you said, it'd be cool to have line as first line argument, so the method should read

def initialize: line array: @array ([]) {
initialize(line, @array)
}
