Beware the Dreaded Dead End!!
summary
The dead_end gem uses ripper to lex and parse source, then runs an outside‑in, uniform‑cost–style search over commented‑out blocks to find the true faulty node, not just where the parser notices failure. It joins trailing slashes, method chains and here‑docs, handles ambiguous cases and multiple errors, exposes a record CLI to replay each search step, and hooks into require to intercept SyntaxError; aims for integration with Ruby 3.2 and returns concrete fix locations instead of vague “unexpected end.”
