Thanks for all your feedback and help. I got a patch that i consider
ready for review. It introduces two new functions:
array_shuffle(anyarray) -> anyarray
array_sample(anyarray, integer) -> anyarray
array_shuffle() shuffles an array (obviously). array_sample() picks n
random elements from an array.
Is someone interested in looking at it? What are the next steps?
Martin
