this simply prints a newline... I expected a runtime error (or better
a compile time error) but it does nothing ... why?
Probably because it's length is zero and therefore isn't actually a
slice
of
the original array at all. It wouldn't surprise me if arr[500 .. 500]
worked
exactly the same way. Because the array is empty, it doesn't really
matter
what values you gave it.
Weird, I was certain that had given me bounds errors before, and so I've
been careful to avoid doing it. Maybe that's changed since I last tried
it.
You get bounds error in debug, but not release.
The bit about slices says you must not depend on bounds checking.
There should be no bounds error in any case, an empty slice is valid.
