It's better to use non-members for operator+, operator-, etc.
In the case of a template class like SafeInt<T>, do you think the binary operator+, operator-, etc., should be friend functions, defined inside the class declaration, or template functions?
I don't think that non-template friends should be defined inline in a class template because they are always supposed to be instantiated regardless of whether they are used or not (unlike ordinary members). For templated operator+, etc, I don't really care.
Note that I've just posted a slightly related ticket on David LeBlanc's SafeInt: "Potential performance gain from non-member operator+" http://safeint.codeplex.com/WorkItem/View.aspx?WorkItemId=7910
BTW, I do think it would be great to have such a library in Boost.
Kind regards, Niels
