Comment(by simonpj):
Thanks for contriubting a patch.
However, I'm not clear of the original intent here. Consider
{{{
data T = T { x,y::Int }
f = T { x = 3 }
g = T {}
}}}
It would be very odd to get a warning from `f` but not from `g`. I'm not
sure this is what the original requester was asking. I thought he didn't
want a warning when `T` had zero fields -- and indeed you don't get a
warning then.
Puzzled.
Simon
