I notice that std.algorithm and std.algorithm.mutate return a
new dynamic array.
Are there any libraries out there that do modifications in
place?
For example, for dynamic array items
```
int[] items = [ 10, 20, 30, 40 ];
// Library call to do in place mutations of items dynamic
array, without any new allocations
items.remove(1);
assert(items == [10, 30, 40];
assert(items.length == 3);
```
It does modify elements in-place, it doesn't modify
`items.length`. Do `items = items.remove(1);`.
Note that remove does not change the length of the original
range directly; instead, it returns the shortened range. If its
return value is not assigned to the original range, the
original range will retain its original length, though its
contents will have changed
