The main difference with Boost.Assert is that the interface allows to 
change the handler at runtime.

By changing it at runtime, it is possible to temporarily make the 
handler throw exceptions, which is how the TEST_ macros are implemented.
They're useful if you want to write unit tests that checks that your 
functions do indeed emit an assert in a situation that is invalid.
