# Final words

That's it.

Remember that if you are unsure about how to implement certain functionality, you can always investigate the sources of real-world metaprograms such as [Datatype99](https://github.com/hirrolot/datatype99) and [Interface99](https://github.com/hirrolot/interface99). Alternatively, you can [submit a GitHub issue](https://github.com/hirrolot/metalang99/issues/new/choose) and I will try to answer as soon as possible.

Happy hacking!
