I think that if you use the HEAD, much of
this will work, if you use the type-equality
notation. But you will probably encounter bugs
too. And in so doing, and reporting them, you'll
be doing us a service.

HEAD, but one obstacle to this is

Ian is fixing that. We'd missed the fact that the bindists weren't being built.
Hold on a day or two.

Simon,
While we're at it, I found a typo in the
http://www.haskell.org/ghc/docs/latest/html/users_guide/win32-dlls.htmldocumentation
page. In
ghc-6.6 the flag to build DLLs was --mk-dll (two leading minus signs), the
new one is -shared (one leading minus sign) but in the doc it's written
--shared
conv :: (a~b) = a - b
conv = id
is there any particular reason that '~' is the symbol for type equality
constraints? I would think '=' would be the obvious choice, (although
perhaps it is already over-used, and is normally asymmetric in Haskell!)?

One of the smaller nits I noticed when looking at profiles generated
by 6.8.1 (using -prof -auto-all) is that class methods show up as cost
centers named something like $f5. I can look at the call stack and
figure out that $f5 is probably the call to a particular class method
