Could the library's interface match a GPGPU implementation?
Creating operations result in shader compilations, so there would
have to be a way to save these operations. Like boost::function<vec(vec, vec)>
for the performance to be worth. Do you see a way to do this with your library?
(This is using a OpenGL implementation).
