Drastic Prelude changes imminent

A lot of people might have opinions about what is good for beginners, but the only opinions that matter are from those who have actually taught a large number of beginners.  I'm not one of them, so I'll keep my beginner opinions to myself.

The haskell2010 package has always been unusable. Initially haskell98 reexposed a subset of base, and they worked together. Then some of the modules were cloned and tweaked, and any time I put them in the same package it all went terribly wrong.

I also have concerns about beginners, but it's clear everyone has radically different opinions about what is good or bad for beginners.

I raised my concerns as soon as I found out about the changes (October 2014), argued my case, made a few blog posts, but seemingly lost. At that point, much like Simon Marlow, I decided to live with it. I have a feeling we might rehash the same discussion every time a new larger set of people find out about the changes, especially as those people are less likely to be connected to the cutting edge of libraries development.

Thanks, Neil
