In our experience, two things that are most likely to break when one is
switching from plain T to 'initialized<T>' are conditional operator ( ? : )
and function template arguments deduction:

int i = 0; 
int j = 0; // changing this to 'initialized<int>' 
           // will break the following code

i > 0 ? i : j; // ambiguous "?" operation
std::max(i, j); // no instance of "max" function template matches the
argument list

Some compilers will accept (incorrectly) the first line, though.
