Without even reading TFA, this was my first thought, remembering back to implementing Fibonnaci's sequence in template metaprogramming from "Thinking in C++, Volume 2": http://web.mit.edu/merolish/ticpp/TicV2.html#_Toc53985733 http://web.mit.edu/merolish/ticpp/TicV2.html#_Toc53985733 It's cool and useful to be sure, but as costrouc pointed out, LAPACK has been optimized for a very long time by some very smart people. Most people who have not studied the field for a bit are unlikely to come across a more optimal method.
