public static final class Cs.ListPattern
extends Object
implements Cs.Pattern

Represents a C# list pattern that matches elements in a list or array against a sequence of patterns.

For example:

     // Simple list patterns
     if (array is [1, 2, 3] lst)
     if (list is [1, _, 3])

     // With designation
     if (points is [(0, 0), (1, 1)] coords)

     // With slices
     if (numbers is [1, .., 5] sequence)
     if (values is [1, 2, .., 8, 9] arr)

     // With subpatterns
     if (points is [(0, 0), (1, 1)])

     // With type patterns
     if (list is [int i, string s] result)

     // In switch expressions
     return array switch {
         [var first, _] arr => arr.Length,
         [1, 2, ..] seq => "starts with 1,2",
         [] empty => "empty",
         _ => "other"
     };

     // With length patterns
     if (array is [> 0, <= 10] valid)
