-/// This declares a list of types which can be allocated by `Arena`.
-///
-/// The `few` modifier will cause allocation to use the shared arena and recording the destructor.
-/// This is faster and more memory efficient if there's only a few allocations of the type.
-/// Leaving `few` out will cause the type to get its own dedicated `TypedArena` which is
-/// faster and more memory efficient if there is lots of allocations.
+/// This higher-order macro declares a list of types which can be allocated by `Arena`.
 ///
 /// Specifying the `decode` modifier will add decode impls for `&T` and `&[T]`,
 /// where `T` is the type listed. These impls will appear in the implement_ty_decoder! macro.
