           Summary: A problem with std.algorithm.remove on array of fixed
                    size array
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



This program works:


import std.stdio: writeln;
import std.algorithm: remove, countUntil;
void main() {
    alias int[] P;
    P[] data = [[1, 2], [3, 4], [5, 6]];
    P x = [3, 4];
    data.remove(data.countUntil(x));
    data.length--;
    writeln(data);
}


Output:

[[1, 2], [5, 6]]



But this fails compiling:

//import std.stdio: writeln;
import std.algorithm: remove, countUntil;
void main() {
    alias int[2] P;
    P[] data = [[1, 2], [3, 4], [5, 6]];
    P x = [3, 4];
    data.remove(data.countUntil(x));
    data.length--;
//    writeln(data);
}
