I am just wondering why ghc writes its output to stderr instead of stdout. In case of an error it might be reasonably but all the ordinary information about chaising and stuff should go to a buffered stream I think.
Why do I care? I start ghc from emacs in a compile window. The output gets displayed and in the case of an unbuffered output the display gets updated for every single character. I don't have to tell you how slow that is.
Yes, at some point we need to clean up GHC's messages and make sure they're all going to the right place. One issue is that if you write some messages to stdout and some to stderr, the order gets permuted randomly, which sometimes isn't what you want. Cheers, Simon
