The patch does add multi-option parsing, but it does not implement dialect-driven formatting semantics as intended. It infers separator style from parsed tokens (`option_style`) rather than from dialect capability, and it does not add a dialect-level switch (like Snowflake-only space-separated support). This can produce different behavior for non-Snowflake dialects (e.g., Generic) versus the intended dialect-specific output rules.
Code Review
The patch partially implements multi-option parsing, but it likely does not fully satisfy the intended dialect-specific behavior because separator selection is stored as mutable per-node state rather than driven by dialect capabilities.
Formatting separator is chosen from `ViewColumnDef.option_style` (default comma) and parser token pattern, not a dialect rule. This can produce comma-separated output for Snowflake when nodes are built/modified without explicitly setting style.
The AST stores options and separator style separately, so they can become inconsistent after transformations (e.g., options changed but style not updated), causing non-canonical or dialect-inappropriate SQL emission.
Adding `option_style` to `ViewColumnDef` forces updates across many struct literals/tests and relies on defaults, instead of a single cohesive options representation that encodes separator mode directly.
