Thanks for your answer.

I don't see the point that the exceptions is re-thrown _automatically_
when it _is_ caught by the constructor...
Because when the exception gets caught by the constructor
function-try-block, the object can be set to a more-or-less "proper" state 
and knows that initialization went wrong, and _maybe_ an exception is
thrown to the caller to signal a problem, but the caller could also
check the state later with another function (maybe bool operator!() const).
