Very valid concerns. If you use C++ it's easy to interoperate with Simit, since Simit is a C++ library with an online compiler that compile the time steppers. You build the graph using a C++ api and then you run a Simit program which updates the graph. It's similar to how you'd use OpenGL or DirectX (graphs instead of meshes and Simit programs instead of shaders). See https://youtu.be/raPkxhHy5ro?t=19m32s, and http://simit-lang.org/api for more information.

You're absolutely right that we could have provided all the functionality as C++ classes instead of compiling Simit programs through the Simit C++ API, and we might at some point. The reason why we didn't do this is that the language is complex enough that we felt it would be less user friendly. I definitely tried to design it as a library without a parser.
