           Summary: In array literals single values can replace arrays of
                    length 1

This program compiles with no errors with dmd 2.047:

int[1][3] a1 = [1, 2, 3];
void main() {
    int[1][3] a2 = [1, 2, 3];
}


But those array literals are wrong. This is the correct program:

int[1][3] a1 = [[1], [2], [3]];
void main() {
    int[1][3] a2 = [[1], [2], [3]];
}


A sloppy syntax is bad because it *always* offers space for bugs, like this
one, dmd compiles this program with no errors (note the missing comma):


int[1][3] a = [[1] [0], [2]];
void main() {}


Now a contains [1, 2, 0], a silent bug.
This situation is partially caused by bug 3849
