D2 code:


inout(int[]) foo(inout int[] data) {
    return data;
}
void main() {
    enum int[] a = [1, 2];
    const r1 = foo(a); // OK
    enum r2 = foo(a); // Not OK
}



DMD 2.055beta gives:

test.d(7): Error: variable test2.main.r2 only fields, parameters or stack based
variables can be inout
test.d(7): Error: cannot evaluate foo([1,2]) at compile time
