I agree with you but these features must be fully vetted before we start
using them in KiCad.  I don't want to use the main branch as a test bed.
 Maybe someone can set up branch just for testing c++11 stuff so that
when we are finally confident that c++11 support is robust enough across
a broad spectrum of compilers we can start merging it into the main branch.
