Fast ByteString Builder

fast-builder's Issues

Support GHC 9

Would this be possible?

Edit: Just tried to compile with --allow-newer. The library builds just fine, but tests blow up with:

tests/prop.hs:97:29: error:

Benchmarks fail to run on GHC 7.10.3

Steps to reproduce:

$ cabal get fast-builder
Unpacking to fast-builder-0.0.0.4/
$ cd fast-builder-0.0.0.4/
$ cabal bench

Benchmarks and results?

In the package description on Hackage, you claim that:

In many benchmarks, the performance improvement is 2x-10x.

Which benchmarks are these? Are there some results we can look at?
