That and if it's not non-templated, it's impossible to have auto ref functions which hide their implementation for those who need to use .di files to hide the implementation. It also might also be necessary if you need to be able to guarantee that the function exists. Basically, any situation where you can't use a template or where it's undesirable to use a template, the current auto ref doesn't work. But the big one is classes, as templated functions can't be virtual. Without a non-templated solution, virtual functions will never be able to do the equivalent of C++'s const& or anything like it, meaning that they'll incur overhead due to unnecessary copies in many cases. - Jonathan M Davis
