This PR adds support for throwing named errors with associated error explanations. In particular, it adds elaborators for the syntax defined in #8649, which use the error-explanation infrastructure added in #8651. This includes completions, hovers, and jump-to-definition for error names. Note that another stage0 rebuild will be required to define explanations using `register_error_explanation`. --------- Co-authored-by: Joachim Breitner <mail@joachim-breitner.de> Co-authored-by: Marc Huisinga <mhuisi@protonmail.com> |
