As time goes on, newer libraries and updates will start to become dependent
upon C++11 features.  This will be a problem for those who work
with compilers which don't yet incorportate the C++11 features.  So
they'll be stuck for a while. And it's not clear from looking at the
library documentation what it depends on.

That's good to hear.  But won't we get a lot of test matrix failures
with a lot of compilers we test with as soon as C++11 features start
getting used? Won't this create a problem that will have to be addressed 
somehow?
