"main=interact id" basically echoes every line of my input, whereas
"main=interact show" correctly waits for EOF before
outputting something.
Which of these are you claiming is wrong?
I guess "interact" does what it should, but I think it should be changed
to avoid interleaved in- and output.

Hi,
For GHC (6.0.1)
"main=interact id" basically echoes every line of my input, whereas
"main=interact show" correctly waits for EOF before outputting something.
Furthermore the buffering mode must be "LineBuffering".
If I explicitely set the buffering to "NoBuffering" I'm not able to
enter EOF
