The ideal metaprogramming framework is an experiment and a work in progress.

Features are missing and not yet implemented; there is no documentation to speak of.

The code is in half-bootstrapped form: the library and the runtime are written in a custom notation, while translator is written in Java.

You can't do anything useful with it, yet.  To track the developments and be notified when the project will reach a more mature state, subscribe to [the announcements mailing list] (https://groups.google.com/group/ideal-announce).

If you want to dive into the code anyway, start [here] (https://raw.githubusercontent.com/google/ideal/master/documentation/here-be-dragons.txt).  If you have questions, email [the developers mailing list] (https://groups.google.com/group/ideal-developers).
