Except that does nothing except calculate values and throw them away 
(since v drops out of scope at the end of the block). x and y are 
unchanged.

Local variables are not objects, and you can't get "references" to them. 
You'd have to do something awful with eval to get the effect you want:

["x", "y"].each { |v| eval "#{v} += z" }
