If we agree on some policy, then we don't need to worry about the
future, because the policy will determine what is going to be admitted
and what not.

But if we agree to require C++11 starting from now, you can go ahead
with your patch, and don't even need the other dialect.  So this
sounds like a win-win solution to me.

The only other thing we need to agree is that we are not going to
switch to a C++ standard newer than C++11, and won't allow code that
doesn't compile with C++11 compilers, until the oldest compiler which
supports that newer standard is at least 3 years old (like GCC 4.8.1
is today).

Does this sound like a compromise everyone can live with?
