+//! _🎵 Immutability never bothered me anyway 🎶_
+//!
+//! This crate provides various "Frozen" collections.
+//!
+//! These are append-only collections where references to entries can be held
+//! on to even across insertions. This is safe because these collections only
+//! support storing data that's present behind some indirection -- i.e. `String`,
+//! `Vec<T>`, `Box<T>`, etc, and they only yield references to the data behind the
+//! allocation (`&str`, `&[T]`, and `&T` respectively)
+//!
+//! The typical use case is having a global cache of strings or other data which the rest of the program borrows from.
