so I noticed DrIFT was generating code like

f Foo{bar} = ...
as seemingly a shorthand for
f Foo{bar = bar} = ...

which does not seem to work with current compilers. I fixed this in
2.0.2 but was curious why it was generating code like that in the first
place. it appears to be illegal looking at the haskell report and I was
uncertain who wrote the derive rules in the first place so thought I
would ask here.
