//! Record bad error messages here which we should improve.
//!
//! Some of these will be good issues for new contributors, or for more
//! experienced contributors who would like a quick issue to fix:
//! - Find where the error is being raised now, generally just search for a part
//!   of the message.
//! - Add `dbg` macros to the code to see what's going on.
//! - Write a better message / find a better place to raise a message.
//! - Run `cargo insta test --accept`, and move the test out of this file into
//!   `test_error_messages.rs`. If it's only partially solved, add a TODO and
//!   make a call for where it should go.
//!
//! Adding bad error messages here is also a welcome contribution. Probably
//! one-issue-per-error-message is not a good way of managing them — there would
//! be a huge number of issues, and it would be difficult to see what's current.
//! So instead, add the error message as a test here.
