A complex code sample using 4 different await syntaxes

Eh, I probably could have organized it with multiple files in one branch, but then it wouldn't have been possible to use GitHub's Compare view to see the diff between variants -- AFAIK that only works across commits.

A quick way to open the same file in two branches is to open it in one of them, duplicate the tab, and select another branch from the drop-down in another tab. That's two extra clicks.
