Hi,<br><br>in fact, if the traits system needs to be extended, we can think about giving some introspection/reflexivity capability to it. But we can go far into that (compile-time, run-time) loosing the goal of uBLAS. But for sure the layout_type is a good idea.<br>

What is the current &quot;state of the union&quot; for the traits system ?<br>Do we need runtime traits alongside compile-time traits (i.e. runtime introspection and reflexivity of our objects ?)<br><br>Cheers,<br>David<br clear="all">
