Nice.
For class templates ADL looks in the namespaces associated with all the template arguments. The result is that an unqualified call to a function that has the same name as one in namespace std can unexpectedly call the std function.
Ok
The strong guarantee is that if the function fails the program state is unchanged. A partially constructed tree doesn't meet this criterion.
You are right. Sorry. Regards, Ion
