This sounds pretty exciting! Can we expect a full fledged stepping debugger integrated with IDEs via https://github.com/phoityne/haskell-debug-adapter <https://github.com/phoityne/haskell-debug-adapter> ? https://github.com/phoityne/ghci-dap <https://github.com/phoityne/ghci-dap> is still quite limited feature-wise.
