public static final class Cs.DiscardPattern extends Object implements Cs.Pattern
Represents a C# discard pattern (_), which matches any value and discards it.

For example: 

     // Simple discard pattern in is expression
     if (obj is _)

     // In switch expressions
     return value switch {
         1 => "one",
         2 => "two",
         _ => "other"    // Discard pattern as default case
     };

     // With relational patterns
     if (value is > 0 and _)

     // In property patterns
     if (obj is { Id: _, Name: "test" })
