One problem with these useful C++ features is that making use of them,
we are wilfully becoming the hostages of a compiler. But the real
existing compilers are struggling even to handle inline functions
without bugs and performance regressions:
    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54965

So I'm leaning to remain conservative and initially use C++ features
only as a debugging aid. Just like OpenMP, gcc vector extensions,
128-bit float types and the other fancy compiler features are only
used (or proposed to be used) in the test suite.
