Could we reduce GHC's surface area by just using haskeline and dumping readline/editline support altogether?
I'm in favor of doing this. For portability and consistency, it's better to have just one version that is unencumbered by these license issues, as long as it works on the main platforms (including Macintosh - has that been tested?). If ghc tries to support both readline and editline, along with haskeline, applications written in Haskell will have different behaviours depending on the combination (platform,line-editor). Better just to simplify.

That's made my day. If I had £1 for every email I've seen in the last decade about platform-related or license-related problems with readline and now editline, I'd be rich man. Super rich. Could we reduce GHC's surface area by just using haskeline and dumping readline/editline support altogether? Yes that might reduce functionality slightly -- readline/editline are complicated for good reasons. But it's increase functionality in other ways (as Judah says), and by giving us one piece of software that we understand, and can distribute with GHC, it might remove a whole class of problems.
