Here are a couple of examples where I don't want to use pipestatus.
Command: false | false; x=0
State after running the command: status=0, pipestatus=(1 1)
Command: true | true; x=$(false)
State after running the command: status=1, pipestatus=(0 0)
In these two examples status comes from x=..., while pipestatus comes
from the previous pipeline.
