I've started a page at 
http://www.haskell.org/haskellwiki/Class_system_extension_proposal
John - I haven't added anything about your class alias proposal because 
you've copyrighted your proposal and I don't want to do the wrong thing ;-) 
Can you add a section for your proposal (or containing a link to your 
proposal) on his page?

Please could everyone who has any other ideas about class system extensions 
add them to the page above so that we have a central location. Hopefully it 
will gradually become clear what all the issues are and perhaps a path for 
trying to implement some extensions in order of difficulty.

Thanks, Brian.
