nested expansion bug with new or arrays

Created by: byteit101

macro str {
  case {_ ($x:ident) } => {
    var y = unwrapSyntax(#{$x});
    return [makeValue(y, #{$x})];
  }
}

macro expand {
    rule { $templName $name }
        => { new foo(str($templName), [str($name)]) }
}

expand worksFine doesNotExpand

should result in new foo('worksFine', ['doesNotExpand'])]); but instead results in new foo('worksFine', [str$49187(doesNotExpand)]);. Removing the new or the [] "fixes" it in that it then expands correctly.
