Hi, this is a draft for a survey for advanced use-cases for variadic generics!

I want to do a proofreading pass and maybe tweak some things to better explain the key concepts (a lot of this survey hinges on explaining these complex ideas very quickly), and then we'll be good to merge.

@PoignardAzur I didn't follow the development of this survey: do you want input from other groups/teams or is the current set of questions finalized?

Any feedback is welcome. Overall this is fairly low-effort because I want to get this out the door quickly, but if you think something can be improved, I'm game.

@PoignardAzur left 2 comments but otherwise we could merge this (maybe squash the commits). You wanted to publish a blog post as well?

I've applied the suggested changes and squashed the commits.

I do want a blog post, thought I'm not sure how the technical details (e.g. link to the survey) work. I'll write a draft.

I will send you the link once the survey is prepared on SurveyHero, I don't think we need anything else.

I've added a "How long have you been using Rust" question. In retrospect it was really silly not to start with that, it seriously changes how you interpret the answers.

Here's the blog post draft: https://hackmd.io/@s_haMSbyTAOWfoXc1aYNUg/BJ1BZ73jle
