The thing is none of the queries in this PR have deep nesting, the default stack in Rust is just not large enough to support what the test harness + recursion is doing even with just a little bit of nesting. The only proper solution I foresee as outlined by @Dandandan is to re-create an AST of ColumnarValues through a heap based stack when walking the tree.
