What does that gate look like in practice?

A sternly-written, notarized letter of indemnification? A bizarro-world sequence of events (like activating Developer Mode on Android)? A game of Galaga which, if played perfectly, unlocks the gate just as doing so unlocks the black car in Ridge Racer on the PSX?

I don't know. It's a gate that allows a person to leave the garden. It exists to be opened, and to be passed through, and also to be closed again -- or to be left open. :)

(The UAC prompt in Windows is also a gate, if existing work is to be studied.)

I know what a gate is for. My question was trying to get you to explain the middle ground between the extremes. That it is hard to visualize/imagine is kind of my point. The UAC prompt is an excellent example of a potential middle ground that is definitely a gate but a near useless one.
