GHC certain *could* do this, but it's arguably not the right thing to do. For performance, the operating system buffers writes until it is ready to write large chunks at a time. If you do not want this behavior, change the buffering mode from its default.
To what? BlockBuffering is worse, not better, and the docs *explicitly* say that switching to NoBuffering will break ^D (if it wasn't broken already...) My specification for a working program is `one that works exactly like every other program on my machine'. I don't see how to produce such a program with GHC.(1) jcc (1) Using readline might work (although I'm kind of sceptical given what's preceded it), but I haven't gotten it to link thus far...
