        Hi, this library might be very useful in a library I'm involved in. Particularly we've developed an interface for linear programing. In the implementation we needed to ensure that this expression compiles: Column x , y; 0 <= x + y <= 10; And this: 0 <= x + y >= 10; does not. We have very ugly solution now and I guess this is a perfect use case for this library. Regards, Piotr
