{code}
function () { // line 1
  print("hello from nashorn");
}

print(this["L:1"]); // print function on line 1
{code}

expected:
undefined

actual:
function () { // line 1
  print("hello from nashorn");
}

{code:title=--print-parse}
[<unknown>] function :program() {
    [|1|];
    var L:1 = [<unknown>] function L:1() {
        [|2|];
        print("hello from nashorn");
    }
    [|5|];
    print(this["L:1"]);
}
{code}

Note that this is a Nashorn syntax extension, and it does not happen if function is assigned to a variable.
