It doesn't solve everything, but I hope we can agree it is an incremental step in the right direction. I don't think a revolutionary change fixing all the issues is feasible. This particular blemish was already being described as "largely historical" more than a decade ago: http://www.haskell.org/pipermail/haskell/2000-October/006147.html Thanks Ian
