My personal take is that adding some way to mark a `ScalarFunction` as being `immutable`, `stable` or `volatile` would be valuable for query optimization (e.g. we could inline/fold `immutable` functions in logical plans, inline/fold `stable` functions in physical plans, and never inline `volatile` functions) -- This is an automated message from the Apache Git Service.
