Hello,
I have got a global constant immutable array:
immutable globalvalues = sort(cast(wstring[])["й", "ц", "ук", "н"]);

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 < b").SortedRange.contains cannot deduce function from argument types !()(wstring) immutable, candidates are:
/dlang/ldc-1.17.0/bin/../import/std/range/package.d(10993):
std.range.SortedRange!(wstring[], "a < b").SortedRange.contains(V)(V value) if (isRandomAccessRange!Range)

Why I can't check?
