Functional Programming in Go

A library of iterators for use with iter.Seq.

// The first 5 natural numbers
numbers := slices.Collect(
	it.Take(it.Count(), 5),
)

// All even numbers
evens := it.Filter(it.Count(), filter.IsEven)

// String representations of integers
numbers := it.Map(it.Count(), strconv.Itoa)
