 Let's say I have an array where @array.end == $end.  Using @array[0..$end] is 
 about 20 times faster than @array[0..*].  I have attached an example script 
 that demonstrates this.bench.p6

If it’s the whole array that you want, have you considered using the zen slice? 
 That is still a lot faster than [0..$end].

Looking at why the * case is so slow.
