Insert adds an element in its sorted position (ascending order).

Collect materializes the list into a slice using slices.Collect (Go 1.23+).

Values returns an iterator over all element values. This follows the slices.Values convention.

Map transforms each element of an iterator using the given function, returning a new iterator. This is a standalone function because Go methods cannot

All returns an iterator over index-value pairs. This follows the slices.All convention (Go 1.23+).
