Subject: Array#[] and Out of Range

Hello.

I'm a bit puzzled by Array#[]'s behaviour. The documentation says
"Returns nil if the index (or starting index) are out of range." which
doesn't explain the following for me:

(x is an arbitrary integer)

[:x][1..x] => []

Isn't index 1 out of range for an array with one element?

[][0..x] => []

Isn't index 0 out of range for an empty array?

I could write more examples, but I hope they illustrate my point.

Thanks,
