So this code has different meanings in C and D:

void main() {
    int *a, b;
}


And to keep the D language simple this is disallowed:

int a[8], c[8];


Then what is this issue asking for?

In Issue 5807 I have suggested to disallow mixing C and D style of array in a
single declaration:

// array of 5 dynamic arrays of ints.
int[][5] c;
int[] c[5];
int c[5][];

Also because of some problems it causes with vector ops syntax:

void main() {
    int[] a1 = [1, 2, 3];
    int[] a2 = new int[3];
    a2[] = a1[];           // OK
    int[3] a3[] = a2[];    // line 5, Error
}


Beside disallowing the mix of C and D syntaxes in a single declaration, another
thing that may be good to do is to perpetually deprecate the C syntax (and do
not turn it into an error).
