One typo, ninety-four errors
A parser was changed to keep going after a syntax error rather than stopping, so that an editor could report every problem in a file at once. The change works. Users start reporting that the compiler has become unusable.
A single missing closing brace at line 30 of a 600-line file produces 94 errors. The first names the real problem. The remaining 93 are things like expected expression, found "}", unknown name "helper" and expected type, found ")", scattered across the rest of the file, and the editor renders all of them.
Name the phase that emitted the 93, and then answer the harder question: is emitting them a bug, or is the bug in what happens to them afterwards? Say what you think a compiler should do with an error it cannot be sure is real.
