Hmm... I'd be tempted to copy them to a single array, but as anon. arrays of value + source - e.g.:
foreach(@a1){
push @all, ['a1', $_];
}
foreach(@a2){
push @all, ['a2', $_];
}
etc...
Then you can sort on @all->[1] and still have access to the original array name (oh, and thinking about it, you could just create references to the original array elements, rather than copying the values).
<update>mediocre minds think alike...</update>
map{$a=1-$_/10;map{$d=$a;$e=$b=$_/20-2;map{($d,$e)=(2*$d*$e+$a,$e**2
-$d**2+$b);$c=$d**2+$e**2>4?$d=8:_}1..50;print$c}0..59;print$/}0..20
