This is at odds with the notion, popular on this list and other
haskell forums, that pure functional programming is the future.
Why is it that every time the topic of teaching basic concepts in
an easier way comes up there are always two or three replies that
say "should we bother? lets filter out the idiots?" These are
pointless and counterproductive. Whether or not you like the idea
of lesser entities sullying your private, pure, functional programming
language, there are going to be a lot more people learning this
language, and there will be people trying to make it easier for them
to learn it.

Many of the best resources for learning Haskell are still academic
papers published by language researchers. We've still got a long
long way to go... Sure there's no shortcut to learning difficult
concepts, but right now its more of a nature hike than a freeway...
