I just love languages and functions that support using a negative int to access array from the end! Awesome.

    ...Never thought of that, but it seems really smart!

    Yep that is really cool.
    Another cool thing I've seen is negative into returning everything but the value.
    So arr[-5] would give you all values but the one at index 5. R does that with vectors for example

    you might want to take a look at python
    and list slices
    they're awesome

    A big problem that comes to mind with this is that you could do it by accident and don't get an OutOfRangeException or similar

    @kaesaecracker not a big problem, man. Sacrificing runtime exception for a powerful feature? I'll take that every day, thank you very much :)
