If you can do some more research into this and confirm it then,
please file a bug report.
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?

Hello,
I have got a global constant immutable array:

Somewhere in program I want to check an existance:
globalvalues.contains("ук"w).writeln;
But get an error:
Error: template std.range.SortedRange!(wstring[], "a <

types !()(wstring) immutable, candidates are:

Why I can't check?
pragma(msg,typeof(globalvalues));
gives immutable(SortedRange!(wstring[], "a < b"))
and
(cast(SortedRange!(wstring[], "a <
b"))globalvalues).contains("ук"w).writeln;
works, so I guess contains doesn't work with immutable?
