Also, the following would not work

#pragma GCC optimize(2) // I don't know whether I got that syntax right
#include <Eigen/Core>
#pragma pop_options

blubb;

Eigen/Core is a separate file so I'd expect the pragma to have no effect on it
no? Or am I wrong here?

You are wrong here the pragma works across header files.


I just talked to some Eigen developers and they seemed to be very favorable to
the idea of a namespace wide option
