[Haskell-cafe] Number 1, at least for now

Yes indeed.  

One thing that would be really helpful, as a first step, would be to
identify a bunch of concrete examples that GHC "should" have optimised,
or perhaps "could" have optimised, and attach them to the GHC wiki
somewhere.  One place would be here
	http://haskell.org/haskellwiki/Performance
or perhaps somewhere on the developers wiki, or as a task.
	http://hackage.haskell.org/trac/ghc

I'm not promising that anything will happen fast (unless someone else
does it!) but it's always much more likely to happen if there's a
specific place that advertises low-hanging performance fruit.
 

This is closely related to the "advice to programmers" that Don
circulated yesterday, in which he explained how he optimised one
particular case.  But not quite the same.
