Worked on the agda/agda2hs repository to enhance the stability of the Agda-to-Haskell compilation process, focusing on robust error handling for dot patterns in module arguments. Addressed a critical bug that previously caused crashes or unclear failures when non-erased dot patterns were encountered, thereby improving build reliability for projects relying on dot pattern matching. The solution involved refining the compilation flow by delaying context argument application until after dot-pattern checks and updating error signaling for module instances. Utilized Haskell and applied expertise in compiler design and error handling to deliver more predictable and maintainable behavior for users of the toolchain.
