As I understand - yes. It doesn't work with immutable object.
Also I see the same problem with 'const' and 'shared' object:
> shared values = sort(cast(wstring[])["й", "ц", "ук", "н"]);
> const values = sort(cast(wstring[])["й", "ц", "ук", "н"]);
> values.contains("ук"w).writeln; // error

So you think it is a bug in compiler?
