Good point, I’ll switch this to return the pair and remove the out parameter.
I’ll apply it in this PR as well to keep the cleanup focused here.
`FunctionWhere::Parameters` is still intentionally optional, as it
distinguishes malformed `Where: {}` from valid `Where: { Parameters: [] }`. The
empty list is an exact zero-parameter selector, while an empty `Where` block
should be diagnosed rather than treated as that selector.
