BTW, making this @safe by changing the manual code to

            static if (isBasicType!U)
            {
                auto d = (() @trusted => _data.arr.ptr[0 .. len + 1])();
                d[len] = cast(Unqual!T) item;
                _data.arr = d;
            }

makes the code twice as slow as the other manual version
