 # Generics parameters of ByRefLike types
 
-Using ByRefLike types in Generic parameters is possible by building upon support added for `ref` fields. Scenarios that would benefit most from this are those involving `Span<T>`. For example, consider the following examples:
+Using ByRefLike types in Generic parameters is possible by building upon support added for `ref` fields. Scenarios that would benefit most from this are those involving `Span<T>`. For example, consider the following:
+
+- `Action<Span<char>>`, `Func<int, Span<byte>>` &ndash; Enables passing and returning `Span<T>` in delegate-based APIs without requiring custom delegate types.
+- `string.Create<TState>(int length, TState state, SpanAction<char, TState> action)` &ndash; Provides a safe and efficient way to create strings from span-based state.
+
+The following are potential future additions (see [Span&lt;Span&lt;T&gt;&gt;](https://github.com/dotnet/csharplang/blob/main/proposals/csharp-13.0/ref-struct-interfaces.md#spanspant) for additional context):
 
 - `Span<TypedReference>` &ndash; Represents the general case where a ByRefLike type is used as a Generic parameter. This specific case would be desirable for a more efficient Reflection API.
 - `Span<Span<char>>` &ndash; Nested `Span<T>` types would be of benefit in the parsing result of strings.

 ## Ref Fields
-To improve the usefulness of ref structs, support for fields which are defined as ByRefs is needed. Currently their functionality can be approximated by Span<T> fields, but not all types can be converted into Span<T> types simply. In order to support these scenarios, support for generalizing ByRef fields, and converting TypedReference, ArgIterator and RuntimeArgumentHandle into following the normal rules of C# ref structs is desired. With this set of changes, it becomes possible to have ByRef fields of T, but support for pointers to ByRef fields or ByRefs to ByRefs is not added to the ECMA specification.

 ### II.10.1.7
 An additional IL keyword, `byreflike`, is introduced to indicate use of ByRefLike types is permitted. This expands the set of permissible types used by this parameters, but limits the potential instructions that can be used on instances of this generic parameter type.
