Why a QuickMetadataPrunedEdge was left out.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SiblingRepeat

The parent that placed the child names it again.

SecondParent

A different parent names a child already placed elsewhere.

BackEdge

A node names itself or one of its own ancestors.

DepthLimit

The parent sits at the tree’s depth limit, so its subtree is cut there (#4689). The child still appears if the walk reaches it by another edge it follows. A containment of a settled node is not followed, even when the limit cuts the path that settles it: settled means aggregated and reached from the root through aggregates and containments of nodes no aggregate names.
