Good point, I forgot about them. Actually I plan to make them official
and remove the "_" prefix.

done.

sure we should have a more careful look at the bug list.

oops, no comment!

That's on purpose. For now I prefer to keep such feature internal
because the fast insertion into a compressed form requires to put the
matrix into a state where you can only do "compressed insertion"
before you call finalize(). This is rather complicated and dangerous
so => internal only !
In the near future I plan to add the possibility to append a raw list
of triplets and let Eigen figures out itself what's the best insertion
strategy. This is the cleanest solution I can think of.
