Not really my decision, but for the most part we are only concerned
with the header. The macro will usually be used to determine the
interface, not the implementation. We generally wouldn't write the
following, as it's easier and less error prone to write just the C++03

void foo() {
    // C++03 implementation
    // C++11 implementation using initializer lists
