I agree that Haskell files should be UTF-8, but I also agree that it is
only relevant for Hackage (and Cabal) and already enforced by ghc-6.12.
The motivation for this proposal can only be that future cabal packages
will use more and more non-ASCII characters as is possible via
LANGUAGE pragma "UnicodeSyntax" (that happens to have no support for "\"
as lambda symbol - probably because lambda is a letter and no symbol!)
However, I think, these extra characters only make sense for corner
cases and should not be recommended for general purposes.
For nicer looking sources I would recommend special viewers or
post-processors (like haddock or hscolour) that translate certain ASCII
sequences to unicode points.
So my view is: Stick to ASCII and only if you must (not just for casual
reasons) use UTF-8.
