 When a method contains a `yield` statement, the evaluation of the method is deferred until the first enumeration. This rule ensures that arguments are validated immediately, while execution of the rest of the method is still deferred.
+This includes explicit `throw` statements for `ArgumentException`-derived exceptions and static `Throw*` helpers on `ArgumentException`-derived types (for example `ArgumentNullException.ThrowIfNull`).
