False positive in unused-output-variable

[anderseknert]

i is here incorrectly flagged as an unused-output-variable:

rule if {
    [i |
        some i
        foo[i]
    ]
}

The issue seems to be isolated to rule bodies, or at least bodies. This isn't flagged:

rule := [i |
    some i
    foo[i]
]

Another false positive found when working with the Gatekeeper Library today:

provided := {annotation | input.review.object.metadata.annotations[annotation]}

Which incorrectly flags annotation as unused
