Well, good enough is perfect in most projects. However, I do like simple
drop-in wrappers that prevent stupid mistakes to ever compile, or that
abort on overflows.

About the construction topic, I think that a good compromise could be to
choose a safe default (always initialize to 0) but to allow one to be
explicitly unsafe:

safe<int> i; // i == 0
safe<int> j(boost::uninitialized); // undefined

It happens that the developer knows that initialization will be done later,
or has already been done (mapped memory for example).
