Maybe a nitpick, but I dislike that Swift Testing snippet defaults to `async throws` test. I prefer starting with the most restrictive type and extend it as needed. I only noticed half my tests were needlessly async throwing hours later, bc the compiler was silent.

Would be really nice to be able to use @Test and #expect in snapshot testing. Particularly @Test for passing in different arguments.
