Yes, but only if the template is not eponymous. > Not sure I am missing anything, but what works when the functions are > named differently from the headline template doesn't work when the > functions are named the same. Yes, when the template is eponymous, the name of the template becomes the name of the eponymous member, and thus effectively hides the other members from outside access. This is actually useful when you want to write a template function with internal implementation details that outside code cannot access no matter what. It's like a little encapsulation unit locked away behind the public-facing eponymous member. I've used this on a few occasions when I wanted template implementation details to be invisible even to other code inside the same module. (Interesting note: you can even stick unittests inside the template block to test internal details, while still keeping said details away from prying eyes in the rest of the module. :-P) T -- Doubtless it is a good thing to have an open mind, but a truly open mind should be open at both ends, like the food-pipe, with the capacity for excretion as well as absorption. -- Northrop Frye
