Responder のコードが長すぎる

let 文のパースを実装する

Parser の定義を複数ファイルに分割する

lib.rs に全部まとめてる現状だとかなり長くて読みにくいため

ネイティブコードへのコンパイルを実装する

とりあえず macOS x86-64 をサポートするために Mach-O 64bit 実行可能ファイルを直接書き出すコンパイラを作りたい

Equal (=) トークンを追加し、レキサで認識できるようにする

言語サーバで都度ソースコード全体をトークナイズし直すのをやめたい

言語サーバ側で、ソースファイルのパスと内容を対にして保存しておき、クライアントから通知される差分をもとにそれを更新して毎回必要最低限のコード断片をトークナイズするようにしたほうが良さそう

Check ワークフローが遅すぎ

cargo-udeps だけ異様に時間がかかっている

毎回やる必要はないので「週一回、コードに変更があった場合にのみ cargo-udeps を実行する」別の定期ワークフローを用意して Check ワークフローからは外したほうが良さそう
