ReusableStringStream holds a std::ostringstream internally, but only exposes the ostream interface. It caches a pool of ostringstreams in a vector which is currently global, but will be made thread-local. Altogether this should enable both runtime and compile-time benefits. although more work is needed to realise the compile time opportunities.
