Some of the parts of the tools mutate the AST while they are doing work on it: for example, while finding lineage we temporarily tag a node with its parents. 

If you happen to try opening the AST outline on such an AST, it will crunch away forever - node linked to parent, process parent, then child, then parent, then child, you get the idea.

We needed to make sure we ignore the parental properties we can set on the AST.
