Think twice before putting empty exception-specifications on functions that
don't throw, then think again:

This will result in no compile-time checking
The run-time behavior is not advantageous
Few compilers can use it for optimization
Even among those that do, it will usually only result in a small reduction
in executable size
Many compilers will use it for pessimization, resulting in a large cost in
executable size and often, speed.
