Read my comment #9. It was *accidentally* accepted in 2.066.1. In git head,
casting T[] to T[n] is generally disallowed (glue layer does not support such
cast operation), and it will be accepted only when the slice bounds are known
at CT. Enhancement 1700 will extend the CT bounds detection, but it's not yet
accepted.
