Passing DBs Through Continuations

A database developer implemented relational algebra operators using continuation-passing style (CPS) to fuse operations and eliminate intermediate materialization overhead. The approach, inspired by functional compiler techniques, allows operators like increment and double to compose directly without producing temporary lists or requiring the complex iterator models used by systems like DuckDB and Umbra. This CPS-based method offers a simpler path to achieving compiled-database-level performance without the engineering effort typically required.
