Dimensional analysis typingThis link describes an implementation of dimensional analysis in C++ using the Boost MPL. What this means is that physical quantities have a type parametrised by a tuple of integers representing the order of physical dimension (i.e. mass, length, time, etc...) with rules determining what operations can be carried out. This is a standard sanity check for equations in physics and easily catches typos. For example the equation for the force acting on two massive bodies is G(m_{1}m_{2})/d^{2}. If this were accidentally entered as This is clearly a useful techniques for say, rocket guidance systems. What other languages are capable of doing this without having to declare a morass of types and functions relating those types to each other?
