please allow me to re-iterate that my proposal is *not* about performance, but about being able to detect and report typical error patterns such as confusing the order of arguments to a function, or to leave out one argument. (Wouldn’t that be great?) I regret pointing out hypothetical and likely insignificant performance effects; it derails the discussion. Your ideas (printing less errors, or less details, at first until asked) can be pursued already now. There is precedent, e.g. https://ghc.haskell.org/trac/ghc/ticket/10848 which added the -freverse-errors option. Options in similar vain (-fone-line-errors, -fnum-errors=1) are worth considering and can be implemented today, so if you feel like it, do explain your ideas in greater detail.
