+## Afterword
+
+If you like the concept and design of the library, then may be we can bring the idea to Crystal!
+There is no need to keep this library, if we can have the same things in standard library.
+And I guess [crystal maintainers won't resist](https://github.com/crystal-lang/crystal/issues/2721#issuecomment-223399683).
+But first we need to get positive feedback to ensure we're moving in the right direction =)
