Also, I really like the idea of writing it in a low level language and then having bindings for something higher. However, unless you plan of having multiple language bindings (e.g., *both* C# and Python), you may want to pick a different route. For example, if you decide to only bind to Python, you can use something like Cython, which would allow you to write pseudo-Python that is still compiled to C. Of course, if you want multiple language bindings, this is likely no longer an option.
