Parameters	Returns
Func<T, bool> predicate IEnumerable<T> source	(IEnumerable<T> Trues, IEnumerable<T> Falses)

Usage

Splitting even and odd numbers

//IEnumerable<int> source = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

var (resultEvens, resultOdds) = 
    source.Partition(value => value % 2 == 0)

//resultEvens = { 2, 4, 6, 8, 10 }
//resultOdds = { 1, 3, 5, 7, 9 }
