          Issue ID: 21555
           Summary: insertBack is wrong and should be tested for
                    Array!bool
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody@puremagic.com
          Reporter: lsferreira169@gmail.com

The given code reports 0 inserted elements and the final array is [false], so this is clearly wrong and should be covered.

import std;

void main()
{
    Array!bool atum;
    writeln(atum.insertBack([false]));
    writeln(atum[]);
}
