Subject: hi, i'm new. plus one question

I've been forced to work on some php lately and found myself  
thinking: "man, this sucks. i wish it was more like supercollider"
then i remembered supercollider is ruby-influenced so i started  
reading about ruby.

Here's my question: is there a common way to rotate a string or an  
array?

I thought i could do some combination of .pop and .unshift or  
something, but i ran into this problem:

idea = ["a","b","c","d"]
x = idea.pop
puts idea

why is idea changed? how do i make it stay the same?
why is it different than:

x = idea.reverse

where idea is left alone and only x is the reversed array?
