The agent patch appears to implement the requested behavior: `START WITH` is optional, `CONNECT BY` can be parsed with either clause order, `CONNECT BY NOCYCLE` is supported, and Oracle `CONNECT_BY_ROOT` is handled via reserved select-item operator keywords. It uses a different AST shape (`Option<ConnectBy>` with optional `start_with` and `no_cycle`) instead of the gold patch’s clause-vector model, but the core intended functionality is covered.
Code Review
Patch likely passes targeted tests and implements key features (`NOCYCLE`, optional `START WITH`, `CONNECT_BY_ROOT`), but it only partially matches the intended flexibility because hierarchical clause ordering is parsed but not faithfully represented/round-tripped.
Although parsing accepts either order, AST/display canonicalize to `START WITH ... CONNECT BY ...`. Queries written as `CONNECT BY ... START WITH ...` are rewritten, which does not fully honor flexible clause-order semantics.
Using `for _ in 0..2` with mutable option flags is less idiomatic and less extensible than parsing a sequence of hierarchical clauses. This increases maintenance cost if grammar variants evolve.
