The patch does not preserve/represent `END TRY` vs `COMMIT` semantics. It changes `Statement::Commit` to carry only `modifier`, so `END TRY` is formatted as `COMMIT TRY` and cannot be distinguished from `COMMIT`. It also parses transaction modifiers for `COMMIT` (and for `END` via start-modifier capability), which broadens syntax beyond intent and misses the dialect-specific `END {TRY|CATCH}` support model in the task.
Code Review
The patch partially adds TRY/CATCH tokens and BEGIN support, but it does not correctly implement END TRY/CATCH semantics and introduces broader COMMIT/END grammar regressions, so it likely does not satisfy the intended change.
The Commit AST no longer distinguishes END syntax, and display formatting emits COMMIT with optional modifier. This fails the intended END TRY / END CATCH support (round-trip and semantics mismatch).
parse_commit now calls parse_transaction_modifier, allowing COMMIT TRY/CATCH (and potentially other modifiers) even though the intended change only adds TRY/CATCH support for BEGIN/END block syntax.
parse_end delegates to parse_transaction_modifier, which is gated by supports_start_transaction_modifier and includes DEFERRED/IMMEDIATE/EXCLUSIVE. This can permit invalid END modifiers and does not isolate END TRY/CATCH support by dialect.
