A new syntax that allows you to specify the default array elements would be nice:
```
array resize [count, default]
```
`default` should be a shallow copy (i.e. if it's an array/hashmap, only the array/hashmap itself should be copied, not the values).
Example 1:
```
_arr = [];
_arr resize [4, []]; //should give [[], [], [], []];
```
Example 2:
```
_arr = [];
_element = [[1,2]];
_arr resize [2, _element];
_arr#0 pushBack 4; //should give: [ [[1,2],4], [1,2[1,2]] ]
_arr#1#0 pushBack 3; //should give: [ [[1,2,3],4], [[1,2,3]] ]
```
