This D2 program shows two problems (dmd 2.048):


void foo(const double[] arr1) {
    arr1[] += 1;      // line 2, no error here
    double[] arr2;
    arr1[] += arr2[]; // line 4, Error here
}
void main() {}


The first problem is at line 2, where the const nature of arr1 is ignored.

The second problem is at line 4, that generates a wrong error message:

test.d(4): Error: invalid array operation arr1[] += cast(const(double[]))arr2[]
(did you forget a [] ?)
