This might be a bit of an oddball question for this forum but I am curious if anyone knows how these work and how to exploit them. From looking at some code it seems that you generate a deeply nested recursive type structure which represents an expression. But how in principle do thing with it like the optimizations you see in Blitz++ and the computations you find in Boost::Spirit at runtime?
