To go off on a tangent, what's the case with
array constructors?

If you have

T tarray[100];

and the constructor for tarray[50] throws,
1. will t[51:99] _not_ be constructed?
2. will the destructors for tarray[0:49] be called?

It would make sense for this to happen, but,
as others have pointed out, C++ behavior isn't
always intuitively obvious. I'd feel better
if a C++ standards Guru explicitly said, "yes" to both.

(Actually, none of my C++ books is a good reference for the nooks
and crannies of exceptions and templates; I've mostly
had to learn by experiment. If we're lucky, maybe
Scott M. will come out with a "Nooks and Crannies
of C++" to complement his "Effective" series.
Maybe more like "Nooks and Crannies of C++, 2010",
"N&CoC++, 2011", etc.)
