Trying to use textbook perfect English often makes the speaker sound stilted and "outdated"- like you are trying to speak like a character in a novel - sounds good in the book or the movie - but you sound a bit odd in real life.
Is it the same for Subjunctive Future and Subjunctive Future Perfect? Is it used in common parlance?
So many dictionaries/grammar books don't have it.
If you purposely don't use the Subjunctive Future in order to sound "street smart" and "current"- how else do you express this notion? Is there a combination of other conjugations with helping words that express the same idea?
