<pre>Clang's constexpr implementation does not perform caching. In C++14, it's not
even clear whether caching will be possible, so it seems like a waste of time
to invest in it now.
Instead, I suggest you remember that constexpr functions can also be used at
runtime, and try not to write functions with exponential runtime.
