It's likely an accepts-invalid bug, meaning it should be a compiler
error instead. I don't think it makes sense that the compiler tries to
slice a fixed-length array of length zero.. tho perhaps it should just
equate that to returning null.
In any case you can return `null` instead of "empty". Fixed-length
arrays of length zero aren't really all that well-defined. Some would
say they make no sense, but there is a weird benefit to them when used
with the built-in hashmaps (a void[0] value type wouldn't allocate
memory, AFAIR and if that is still true).
