//! Transformations that derive new logical-plan pieces (schemas,
//! filters) from existing ones by lifting symbol-level transforms
//! over their members.
//!
//! The level rule: a transform lives at the level of what it takes as
//! input. Symbol-to-symbol transforms belong to
//! `planner::symbols::transforms`; anything that rewrites a plan-level
//! container of symbols belongs here.
