Re: [eigen] Bye bye "Eigen/CXX11", welcome "EIGEN_CPPYY_ONLY" ?

["Wood, Tobias" <tobias.wood@xxxxxxxxx>]

I heartily +1 this proposal.

 

(I embraced C++11 sometime ago, so in my book anything that makes using it easier is a good thing)

right, let's forgot about this minor remark then.

 

 

btw, this idea came from bug 1210 [1] , where Christoph just suggested to use a single EIGEN_MAX_CPP_LEVEL macro that a user could define to 03, 11, 14, etc. (instead of numerous EIGEN_CPPYY_ONLY) . This is definitely much better and simpler.
