in reply to Idiom to return 0 or random number of array elements

I can then extend that to return a random number of elements: @array[0 .. int rand @array];. But I need to also sometimes get 0 elements.

That will return 0 elements approx. 10% of the time:

@array = 0 .. 9;; sub x{ return @array[ 0 .. int( rand @array ) ]; };; $stats{ scalar( x() ) }++ for 1 .. 1000;; pp \%stats;; { "0" => 90, 1 => 103, 2 => 126, 3 => 99, 4 => 101, 5 => 101, 6 => 88, + 7 => 97, 8 => 105, 9 => 90 }

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

RIP Neil Armstrong
