In order to make user code reasonably fast in debug mode, the idea would be to add a compile time EIGEN_FORCE_INLINING option that would add the always inline attribute to all simple eigen functions. This means that all simple functions should be qualified with at least an EIGEN_INLINE macro that would default to inline, and EIGEN_ALWAYS_INLINE_ATTRIB if EIGEN_FORCE_INLINING is defined.
