Some reasons *not* to use it | are: it has an awkward license, it's big, it needs updating, and we run | into problems when the Haskell program wants to use GMP itself via the | FFI (it's possible by essentially renaming everything in our local copy | of GMP so it doesn't conflict, but we haven't done that). In fact, we have long wanted to replace GMP with another library for exactly these reasons. It's a nice, well-specified, self-contained project, which is just waiting for someone to step up and do it. Of course, we'd only want to replace GMP if the alternative was also fast and reliable. If anyone is interested in tackling this, let us know! Simon
