Some further wisdom (by which I mean "funny quotes from class not meant to be taken seriously, and not guaranteed to be error-free") from Crary:
"I like deBruijn* more than I used to...
Actually, deBruijn is a guy, I know him...
Actually, I don't like him..."
*meaning "deBruijn-style nameless lambda terms"
