Array::Circular - add "is circular" trait to Arrays


use Array::Circular;

my @a is circular(3);  # limit to 3 elements


This module adds a is circular trait to Arrays. This limits the size of the array to the given number of elements, similar to shaped arrays. However, unlike shaped arrays, you can push, append, unshift and prepend to arrays with the is circular trait. Then, if the resulting size of the array is larger than the given size, elements will be removed "from the other end" until the array has the given size again.


At this moment, it it only possible to specify the size of a circular array at compile time.

If you like this module, or what I’m doing more generally, committing to a small sponsorship would mean a great deal to me!
