The AST used by SQLite changes. Frequently. If we provide an interface that returns the AST as a (virtual) table, that would make the AST an interface, and prevent us from enhancing it in the future, for new features or performance improvements. Furthermore, the current AST for Fossil is rather non-intuitive. It is not a straight-forward translation of the SQL, but rather employs many tricks and hacks to make it small and fast. If it were available to you, it would require a great deal of documentation to understand and even then might not be helpful. -- D.
