C++ might, but lots of experts with real life experience of C++ in cases
where exception-during-construction is real and problematic suggest that
the init-with-ctor doesn't fit well in that scenario. There are other
cases where it doesn't fit either (for example, deserializing from
something like XML which tends to promote HAS-A relationships but your
objects are all inheritance based (IS-A)).

i agree with you that if its not so much of an issue, then you
suggestion of:

    MyFancyWidget* w = 0;

    try {
        w = manage (new MyFancyWidget(some, args, it, might, need));
    }
    catch (....

is perfectly sensible.
