          Issue ID: 13799
           Summary: Whole-array initialization for static fixed-size
                    arrays of arrays too
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com

Please allow the missing common case too:


int[2][2] m1 = [[1, 1], [1, 1]]; // OK
int[2][2] m2 = 1; // Error
void main() {
    int[2][2] m3 = [[1, 1], [1, 1]]; // OK
    int[2][2] m4 = 1; // OK
}


dmd 2.067alpha:

test.d(2,16): Error: cannot implicitly convert expression (1) of type int to
int[2][2]


It's expecially useful when the size is a compile-time constant defined
elsewhere that is not known locally:

enum N = 5;
int[N][N] m = 1; // Error
void main() {}
