<h2>Are AA value pointers invalidated by AA mutation?</h2>

In other words, does this program run without error?

<div class="language-d"><verbatim>
void main() {
    int[int] aa = [1: 2];
    int* p = 1 in aa;
    foreach (i; 3 .. 10_000_000)
        aa[i] = i;
    assert(aa.length == 10_000_000 - 2);
    assert(aa[1] == 2);
    assert(p == (1 in aa));
}


There's no error, despite it reallocating the AA after the pointer is taken, because the pointer is to an individually allocated bucket, rather than a pointer into the resized backing array.
