I don't know how well requiring newer versions upon discovery of a 
problem is going to work in practice. Given the cost that upgrading a 
production compiler can have, this may be met with resistance (although 
would be the best option from our point of view).

My question remains:
What level of confidence do we have that the C++14 support in the 
proposed compilers is actually sufficient for clang/llvm?  Do we have 
any anecdotal evidence that they have been used in actual projects with 
success?
