The “repeat” directive is just a shim to create arrays of _entries_. We may remove this from the interface in the future, but we do need it to function as expected in the interim! Most callers rely on just the first “value” argument, but there’s no good reason not to expose the `(value, index, array)`-triple that a standard callback would receive from “Array.map”.

FYI —Added this test first to prove that we could repro failure in our test suite. Then, added the related fix.

Super simple fix to just pass everything through as-is.

FYI @klebba — noticed this one while I was working today. It was a quick fix, so I figured I’d throw in a quick update. |
