(I don't know where to file this, so I open a new bug report, sorry if it is a
duplicated.)

I'd like DMD 2.047 to catch this bug at compile time (so this is more an
enhancement request):

import std.stdio: writeln;
void main() {
    double[] a = [1];
    writeln(a[] + 1); // access violation
}

----------------

This prints nothing and raises no compile-time or run-time errors (this is more
like a bug):

import std.stdio: writeln;
void main() {
    int[] a1 = [1, 2];
    int[] a2 = [3, 4];
    int[] a3;
    a3[] = a1[] + a2[];
    writeln(a3);
}
