Correct task syntax?

Hi there, I'm using cue v0.2.0

I've seen at least 3 separate ways to write a task across the cue git repo

Option A as seen here here

command: hello: task: hello: {
  kind: "print"
  text: "hello"
}

Option B as seen here

command: hello: task: hello: cli.Print & {
  text: "hello"
}

Option C as seen here

command hello: task hello: cli.Print({
  text: "hello"
})

Option C throws an error when I use the example included in that documentation. Options A & B both work, but this documentation refers to the kind field as legacy with support for now. Based on this, and the output from cue help cmd I'm pretty confident that Option B is the correct syntax, but am looking for confirmation.

Thanks!

Option C uses a lot of old and deprecated syntax. This documentation really should be generated.

The same holds for Option A. That should still work, but only as a grandfathered legacy style.

So you're right: Option B is the canonical way of writing things.
