Great point, that bothers me, too. The convention in the standard library
is to use size_t as indices, which means one has to keep in mind that
looping over Eigen objects requires Eigen::DenseIndex.
Just adding a note regarding size_t:
We decided to use ptrdiff_t instead of size_t for various internal
design reasons. Independent from whether size_t would have any actual
benefits here, it's definitely too late to change that now. Most
importantly, this would generate sign-conversion warnings for users with
code that has been valid for a long time.
