Friendly Ferris: Developing Kind Compiler Errors
summary
Improving rustc diagnostics by changing the compiler itself (not just phrasing) to act more like a tutor: producing sensible standalone errors, focusing on common cases, recovering from error states so later checks still run, and hiding cascading errors. Concrete work includes clearer lifetime and type diagnostics, small code-transform fixes that let compilation continue, and community patches integrated quickly (within about six months).
