Thread: Function name as template parameter?

Is it possible to pass a function name as a template parameter? Here's an abstraction of what I'm trying to do. Another possible complication is that I'm trying to assign a default function that is part of a namespace:

Code:

namespace foo{
    void fighter();
}

template <function = foo::fighter>
class a_class;

What do you mean, here? You don't ever specify anything about a typename when you declare a template.

Yes, I do. That was just an abstraction.

And the compiler accepted that, so I guess that was it. Thanks.
