remove deprecated whiny nil related code
Wait, whiny nils themselves are being deprecated? I thought it was only the "smart" additional whiners (e.g. ActiveRecord) that caused the 1.9 performance problem. Removing fail-fast code like whiny nils seems like a bad idea.
ah, didn't realize nil.id was 1.8-only. Too bad.. maybe @tenderlove can add a performant boxed NilClass to Ruby 2.0.
