I find the former syntax clearer and more readable, actually.

I'll implement this syntax instead and then write up a Haskell' proposal.

I am sure that it was already argued at great length, but I think it is wrong to start the declaration with "deriving." I believe that "derive instance" fits much better into the language. I understand the desire to avoid adding new keywords but I think that something along the lines of what was done for "for" could be done here for "derive." Regards, Brian
