//! This module contains utilities for working with properties where the specific property in use
//! is not known at compile time.
//!
//! For regex engines, [`crate::sets::load_for_ecma262_unstable()`] is a convenient API for working
//! with properties at runtime tailored for the use case of ECMA262-compatible regex engines.
