- Subject changed from array syntax for referencing parent or child nodes to array syntax for referencing parent, child or sibling nodes
It is common to use chaining to reference parent nodes. Instead of copy.parent.parent.parent or copy.getAncestor(3) we could provide syntax like copy.parent[2] for "upward access".
Child nodes are often referenced using node.getChildAt(x) but we could provide access to children via node.child[x].
Sibling nodes might also benefit from this idea. Instead of node.nextSibling.nextSibling it could be node.sibling[1].
The only slightly inconsistent part here is that parent access would be "vertical" and the sibling/child access would be "horizontal".
