//! Source management and structured diagnostics for the Deed compiler.
//!
//! Nothing here knows anything about the Deed language. It exists so that no
//! part of the compiler ever has a reason to return an error as a string.
//!
//! [`hashing`] is the odd one out and it is here because [`Span`] is: every
//! pass keys a map by one, and the hash they are looked up with is a property
//! of the key rather than of the pass.
