Comment (by guest):
I agree with the bug report, it's bitten me a few times, and note that
using hFlush requires importing System.IO which should not be required in
these very simple programs.
main = do { putStr "Enter your name: "; name <- getLine; print $ "hello ++
name }
is one the first programs anyone writes in any language and it shouldn't
require a bunch of web searching to find out what is wrong and how to fix
it.
