Re: [Haskell-cafe] Best practices for linting wrt performance

It was part of some CPP so I guessed that was the only reason. There's no indication that this code should act like seq https://github.com/bos/aeson/commit/f25ac48afd3534f3b951140e448061bea83b7d28... On Sun, 19 Mar 2017 at 21:24 Oliver Charles wrote:

Is that "redundant case" actually acting like seq?

Thanks Joachim! I actually found a note about that in the aeson sources so I'm using

ignore "Avoid lambda" ignore "Eta reduce"

The best way to find an answer to this for aeson is of course to run the benchmarks, but are there any rules-of-thumb that you take into account when linting?

eta-reduction can increase sharing but can also increase the cost of a function call, so that’s something to be careful about.
