Prior Nacre V,
I generally don't like passing whole arrays

Neither do I. But what you did is likely even more work than passing the whole array. Your code is equivalent to the following:

To avoid making copies and only passing a reference, that should have been by_groups_of( 3, \@array ). Additionally, an iterator should stop when it is finished. In your code, you have to explicitly force it to abandon the infinite loop.

I do appreciate the reply and finding the fencepost bug. See this node for the latest version.

Cheers - L~R
