Personally, I think using # is way more descriptive than $... $ looks like a php variable.. some might say # looks like a cold fusion varaible, but honestly, cold fusion is crap, so I just ignore it...

# also seems like "number of elements"... $ has no other natural meaning...

list[# - 5 .. #]

should give you the last 5 elements of the array.

Also, I have another idea. using "..." should mean, to the end. so

list[4 ...]

means, from 4 on. so...

list[# - 5 ...]

means, the last 5 :)

Just an idea. Won't break existing code.

You have my vote. I agree wholeheartedly.

I also like this idea. To make it simpler we could just use .. and leave one (or both) of the ends blank. So that:

array[a ..] == array[a .. #];
array[.. b] == array[0 .. b];
array[..]   == array[0 .. #] == array;

Just thinking out loud.

I dont mind $, that said, I don't mind # either.

This idea has been proposed before, along with many others. Do a search, you'll see what I mean.
