Re: [boost] Review Request: QVM (generic Quaternion, Vector and Matrix operations library)

Q: Why doesn't QVM use [] or () to access vector and matrix elements?

A: Because it's designed to work with user-defined types, and the C++ standard requires these operators to be members. Of course if a user-defined type defines operator[] or operator() they are available for use with other QVM functions, but the generic access defined by QVM uses operator% instead.

Emil, correct me if I'm wrong. For higher dimensions the user would be forced to use traits explicitly: qvm::v_traits::r<I>(vec); qvm::m_traits::r(mat); It'd also probably be possible to add a free function get, now or later if the users requested it: qvm::get<I>(vec); qvm::get(mat); There are std::get, boost::get and boost::geometry::get serving similar purpose so it should be intuitive.
