I don't think it's a bug. --++ is a valid operator, whereas --
introduces a comment.
In GHCI:
Prelude> let (--++) = (+) in 5 --++ 6
11
Hope this helps,

Hi,
I got an error if one of lines reads "--++ bla bla bla" where I tried to comment, but "-- ++ bla bla bla" (notice the space after "--") is OK.
Do you think this revealed a tiny bug in the GHC compiler (I am using Windows Haskell Platform 2009.2.0.2)?
Thanks,
Hong
