There are no downloads yet. At the time of writing (2012-01-22) I'm done designing the language and its implementation. So I will start coding from this point. I have decided I'm going to release the project under the GPLv3. I intend to try to make it an official GNU-project, if (and only if) it proves itself useful to other people, and exceeds its value as experimental language learning ground for me.
I'm going to host the code on Savannah and I'll be developing it in C and Guile. At first I intended to develop Asha in Haskell and regarding the nature of the project this would probably be more convenient. However, this language is not widely used in the GNU community, so I think it's best to stick to the defaults and common denominator of most GNU projects.
