It's a problem with buffering:
hSetBuffering stdin NoBuffering
This usually doesn't work on Windows:
GHC 6.4.2 and 6.6: requires <enter>
Hugs (console) Sept. 2006: requires <enter>
WinHugs (GUI) Sept. 2006: works as expected
But it seems to work on Linux:
GHC 6.4.1 on Ubuntu 6.06: works as expected
GHC 6.6 on Ubuntu 6.06: works as expected
I am really interested in hearing of a solution that works on all platforms.
