There's a couple problems with implementing that: 1. Dynamic outputs means you can't even know that number. You could assume that each dynamic output is just one action, but that's...

If you intend for the `out` artifact to be a directory, then you definitely need to declare it with `dir = True`, and buck is right to make you do...

Back from travel. I asked about this, and it would indeed be possible to support projecting through symlinks, at least external symlinks. However, it's a bit of a refactor because...

@thoughtpolice you could imagine doing this in a `dynamic_outputs` like way. Imagine essentially the exact same API that `dynamic_outputs` has today, except that on the call to `dynamic_outputs` you also...

(I'll respond to that last message in the PR)
