I would argue for a third audience (though arguably a subset of the 2nd case above): 3. The person modifying the function. They have to know whether or not it is a template or a specific concrete type. We can say that, if a person changes a function without first determining that and causes a regression, well shame on them. I think that is fair. But I think we can do better by offering a little assistance. Tom. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Discussion" group.
