I wrote a pretty detailed blog article about the motivations and some design aspects of the project. If you want to play with a new little toy, I'd love any (constructive!) feedback, bug reports, pull requests, etc.
Have you seen http://terralang.org ? With a little work, your DSL could be generating stand-alone, statically compiled executables and c-linkable libs :D
Oh, I hadn't heard of that. Sounds interesting... I've also considered at some point switching to an LLVM backend, which would let me JIT on the fly or build executables.
