And I thought, hmm, that is really odd grammar: nominative pronoun with infinitive verb. Had anyone thought about this expression of subjunctive mood in English before? It had never stood out to me before.
We were taught the subjunctive (in all tenses) explicitly in English class when I was in grade school and high school.
Language Log has a couple of good articles on why, from a cross-linguistic perspective, "subjunctive" isn't the best term for these forms: http://itre.cis.upenn.edu/~myl/languagelog/archives/001192.html
