Reversing arrays

Reversing arrays

[David Gómez]

Hi all,

Does zsh support some method to reverse an array? I've been looking at the
subscript flags, but none of them seems to reverse an array, although it's
seems there has been some discussion, looking through the archives, about
this issue in the list some time ago. 

Thanks,

4.1.1 supports ${(Oa)array} (O = reverse of the order specified in the
next flag, a = normal array order).

4.1.1 is *definitely* coming Real Soon Now.

I'm using test1. Right now i've tested it and it works ok. I thought it
wasn't supported because i didn't see anything in the documentation.
