Side Enum

Defines a place relative to sibling. The "outside" of a trait is the undefined sibling, so After undefined is the beginning of the trait, and before undefined is the end.

For this purpose, traits look like:

{undefined} - {Node 0} - {Node 1} - ... - {Node N} - {undefined}

Each {value} in the diagram is a possible sibling, which is either a Node or undefined. Each - in the above diagram is a Place, and can be describe as being After a particular {sibling} or Before it. This means that After {undefined} means the same Place as before the first node and Before {undefined} means the Place after the last Node.

Each place can be specified, (aka 'anchored') in two ways (relative to the sibling before or after): the choice of which way to anchor a place only matters when the kept across an edit, and thus evaluated in multiple contexts where the two place description may no longer evaluate to the same place.
