I've just started learning D and noticed a bug, but wanted to
confirm it here before reporting it.
According to spec: "If the new array length is shorter, the array
is not reallocated, and no data is copied. It is equivalent to
slicing the array". Contradicted by a trivial program:
void main() {
int[] arr;
arr.length = 7;
arr.length = 6; // not ok -- allocation
int[] slice = arr[0..5]; // ok -- no allocation
}
