Eric Milles commented on GROOVY-8726:
-------------------------------------
The reason I cite other AST nodes as a precedent is all the back references
that do exist in Groovy make navigating a heap dump incredibly difficult.
Starting from a ModuleNode, it is very hard to see who holds the reference that
is preventing GC because the module referes to SourceUnit and ResolveVisitor,
etc. and many of them end up with references back to ModuleNode.
Any {{AnnotatedNode}} can produce its declaring class. From there, you can use
a CodeVisitor to discover any ancestor or sibling relationship you may need.
