My impression is that the strong guarantee is very rare in library and 
insert
provides a basic one (for instance, in various places in the 
implementation of
<vector> you may find copy/move operations intermixed with _Construct: 
if the
latter throws the catch only frees the memory)

While we are at it: what do people think, in general, about a large 
scale QoI
project aimed at providing the strong guarantee wherever possible?
