It may be that we still compile with gcc 6, which has bits of C++17. I 
feel a bit lazy to check this, but I could in principle. I would say 
that we allow ourselves to use every C++17 feature and see afterward 
what compiler supports it (provided that it is not later than gcc 8). Is 
that a clear policy?

I just checked the status, it seems that we need gcc 7 for <any>.

What about requiring gcc 7?
