Commits to ANI stopped nearly two years ago. Maybe you should still try?

You would learn a lot and that would make you a better programmer.

or just contribute to ANI, if you don't want to reinvent the wheel.

Reinventing the wheel would teach me more, I think. But ANI is a useful reference for how to do some things.

I've been greatly interested in ANI-like dataflow programming languages for a long time now (though maybe not with ANI's crazy syntax). I would encourage you to give it a try! Don't let the existence of other languages hold you off (and in any case, ANI can be considered dead).

So contribute to it!

Take it and improve on it. I'd also experimented with puzzling out a syntax for a language like this and it's very exciting to see something that actually does it. Read through the tutorial. The syntax looks awful but is actually very coherent once you get into it. As an aside, getting there first doesn't matter. Doing it best is what matters in the long run. Apple, google, Facebook, etc.
