Andrew worked really hard and addressed the voiced concerns with the way
chaining was done. In my last read through I found a bunch of stylistic
quibbles and a question about behaviour where reading the spec confirmed
that the current implementation is actually correct ( grouping sets +
functional dependencies => weird).
I plan to post a squashed patches from what's in git now in a couple
hours and then, unless something major (issues, protest) comes up, push
PDT late afternoon.
