Not-So-Boring Haskell
summary
Argues for a workflow that keeps production pinned but use GHC head in development, pin production so upgrades take days not years; warns that avoid Template Haskell and GHC plugins because they break silently and are unfixable without author help; recommends favor hole-driven development with many fine-grained types, avoid ad hoc overloading like overloaded lists/strings and avoid proliferating type classes with associated families; prefer explicit imports, bangs on data fields rather than StrictData, and prefer GHC generics or simple CPP for stable boilerplate.
