Switzerland is not in the EU.

It's not and that's fine, but it's very much part of the European economic area, and we have a great relationship as well as a lot of alignments with standards and so on. The EU wouldn't have no issues taking notes from the Swiss.

Switzerland is not part of the European economic area, aka EEA.

It formally isn't but for (almost) all intents and purposes it is.

While it's not part of the EU as a member, Switzerland is quite literally in the EU.

You can escape Switzerland by going straight up into space. It's only "in" the EU in 2 dimensions, maybe 2.5 since you can't dig your way out.

Ah, that's what they're building the power plants for. Blasting things into space.

Just the opposite. It's literally not in the EU. It's literally in Europe but not in the EU.

I like that you ignore that “in” means “inside” in one sentence and then use that exact meaning of the word in the following sentence

OP was making a geometric observation.

By that light, the UK is still in the EU. I bet they would disagree though.
