Of note with this one, we have a bit of a timing challenge: we should merge after the release with the feature goes out since the samples are treated as a live resource BUT we must merge before the release with the feature goes out so that the embedded samples have the new syntax. I think this means we have to hit that window of merging just before we know we are going to do an official release.

This sample also shows the copy and update syntax for structs. Is this intentionally deleted?

[ScottCarda-MS]

We should probably have two new samples to replace this file: one for the copy syntax of structs and a separate one for the array index assignment.

@swernli why, what do you have in mind when you say "live resource"? Do we have direct links to the main of this repo from documentation?

Yeah, last I checked we do. We still get referrals from learn.microsoft.com and quantum.microsoft.com, and I believe the learn site still deep links to the samples folder. It's possible those links have changed since I last looked though.

We need to also consider that QCOM takes new packages and updates katas and samples regularly from them, but doesn't always update the engine/compiler when they take a new drop, so we'll need to coordinate with them to ensure we dont check in unless they'll be updating content and the compiler.

Changes look good to me!

Closing for now, keeping the branch and will reopen when/if this is rebased and ready to move forward.
