## Summary The issue references the extremely resource heavy type family example that I shortly presented at the end of HIW 2026. We originally encountered this issue in https://github.com/clash-lang/clash-crypto, but also created a stripped-down reproducer at https://github.com/kleinreact/clash-crypto-etfr, only depending on `base`. ## Steps to reproduce ``` git clone https://github.com/kleinreact/clash-crypto-etfr cd clash-crypto-etfr cabal build ``` ## Expected behavior The reproducer shall build within less then a minute and shall only require a reasonable amount of memory. However, currently it takes more than a minute to compile and requires almost 16GB of RAM. ## Environment * GHC version used: 9.10.3 (livelock), 9.12.4 (livelock), 9.14.1 (OOM)
