+//! rmode — `RMODE <channel> <listmode> [pattern]`, bulk-remove entries from a
+//! channel list mode (`b` bans, `e` ban exceptions, `I` invite exceptions). With a
+//! `pattern` glob only matching entries are cleared; without one, all are. Needs
+//! half-op+ (opers bypass). The removals go through the normal mode engine (chunked
+//! to keep each `MODE` line legal), so they broadcast and propagate like any other.
+//!
+//! Behaviour reference: InspIRCd's `m_rmode`. Original native Rust.
