I will say only that it seems almost like colourful sayings have become somehow imbued with transformative power. "Rob Ford! That guy's on crack!" And voilà! HE IS. Instead of his behaviour inspiring the "That guy's on crack!" because that comment is appropriate because HE IS ON CRACK, it felt like that comment itself might have made the crack smoking happen. It's like figurative language might have started to have literal effects. "Rob Ford! That guy's bananas!"
"As with the future perfect, [future perfect progressive] combines concepts of both the future and the past. Imagine that some scenario is happening right now, at the present time, and will continue to happen for some time into the future. Or, the scenario has not yet begun, but it will, and once it does, it will continue for some time. Hold that thought. Now, imagine jumping into the future while this scenario is still is progress, looking back on it, and observing how long it has been in progress at that point. That is the future perfect progressive."
