Ah, thanks a lot for finding this link! This is enough to make me OK
to make this assumption.
If I understand well, your aim is to make Eigen::Complex entirely
interoperable with std::complex, and the tricky part was indeed to
handle pointers, good job.
(I'm not yet able to really review anything).
