Perhaps this has already been discussed at length, in which case I apologize but, well, why provide line input editing at all? A number of languages/programs (off the top of my head: sml, most Schemes) don't; the standard method to get line editing is rlwrap. And this works (in my limited experience) quite well. The disadvantage as I see it of using editline or Haskeline or whatever is that it's going to be sutbly different than other methods; presumably, people won't like the changes in behavior. It seems to me that from a UNIX-y separation of concern view, the right thing to do (as many languages have chosen) is to /not/ provide line editing, and just let the user do that with any number of convenient tools that focus on getting/that/ right (like rlwrap.) Is there a reason we've not taken that approach?
