Well, if we are talking about rationale and programming style, then authors like Lippman/Lajoie/Moo in general advice against overloading operator, (14.1.1). But really, now the point seems to me rather clear: it is essentially impossible to "protect" the library vs all the possible operator overloadings in global namespace (consider also things like operator|| and operator&&) together with unrestricted templates (thus "enabled" not only for user defined types): if the user does that then has to accept the behavior he gets. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26974
