Subject: Q: Shifting a hash anf and array

Hi,

 I am looking for a neat "trick" to shift the contents of an array and
 an hash. I know, that this is more or less explicitely programmable
 in a few lines, but may be there is something faster, trickier, nicer
 than that. It should work like this:

 Contents of the array before the trick:

 1 2 3 4 5 6 7 8 9 0        index
 A B C D E F G H I J		contents

 (execute *trick*)

 Contents of the array after the trick:

 1 2 3 4 5 6 7 8 9 0        index
 J A B C D E F G H I		contents



 And now the shift of an hash:

 Contents of the hash before the trick:

 A B C D E F G H I J		key
 1 2 3 4 5 6 7 8 9 0        value


 (execute *trick*)

 Contents of the hash after the trick:

 A B C D E F G H I J		key
 0 1 2 3 4 5 6 7 8 9        value


 Both are very similiar. 

 I am curious, how "compressed" and/or "tricky" a working code can be to do the
 *trick*.... :)

 (I know, that this most often does not result in "good code" or
 "something which can be taken as an example for master
 programming" :) ...but I always intersted in "thinking tricky" ... 
 just for the fun of it and for the production release :)))

 Thank you very much fro any idea!

 Ruby.use!
