Hello!

As of last week:
- I finished the Context class, which is providing information 
about the error token, its location, and the expected tokens. It 
is currently under review. [0]
- I implemented the custom error message functionality. It is 
currently under review. [0]
- I almost finished the lookahead correction feature, I expect it 
to be ready by the next update. [1]
- I made the requested changes for the PR for dlang/phobos. [2]

The plan for next week:
- Continue working on lookahead correction.
- Add tests for programs that use multiple parsers.
- Implement yyerrok, which is a way to make the parser resume to 
normal execution immediately after it encountered an error. [3]
