Will do, if you also start assuming good faith on my part.

OK.  I'll take that in consideration.

I think worrying about language version requirements is seeing
it backwards from what we should be looking at.  IMO, we should
be looking at the distribution sphere (and the distro versions people
are likely to be using/developing on, e.g., latest Ubuntu LTS, past
couple Fedora releases, etc.), and check what are the compiler versions
that  are shipped in them, either by default or as optional packages.
And then from that, decide which most up to date language version / 
features we can require (if we'd really want to use them).  I.e., if in 
5 years, virtually everyone has convenient access to an C++14 compiler, 
why not make use of C++14 features if they'd make our lives easier?
