A scope-aware variant of OwnedVisitor.

Every visit method receives an OwnedScope describing the lexical context at that node. Drive traversal with OwnedScopeWalker.

Required Associated Types

type Break

Value carried by ControlFlow::Break when a visit stops the walk early; use () to stop without a result.
