$a->eq(-n) not on documentation nor the cheatsheet

[diogo]

Just used the form $a->eq(-n) to choose the element that is before the last in an array ($a->eq(-2)) and it works, but it's not mentioned on the arrays page of the documentation http://processwire.com/api/arrays/ and, naturally, neither on the cheatsheet.

It's somehow assumed, as the php equivalents you can also use -n, array_slice or substr etc.

Some people are learning php while working with pw, I'm doing it myself. I think it would be better if things like this would be explicit on the documentation.

New things get added too. Once 2.3 is out, I'm going to try and go through everything and track down what new stuff should be added to the docs and cheatsheet. I think eq() has been there since the beginning, though it's admittedly one I don't use often (easy to forget it's there).
