Multiple functions using the same template?

Is it possible to include more than one function in the same template instead of rewriting the template twice? Like if you were writing:

template <typename T>
void A() {
    //...
}

template <typename T>
void B() {
    //...
}

Those are not the same function, but they share a similar template (using the generic type T). Is there a way to initialize the template only once?

Grouping them inside a class template would achieve that.

template <class T>
struct Functions {
    static void A() { /*...*/ }
    static void B() { /*...*/ }
};

However, you lose the ability to deduce T from the functions' arguments, and the calling syntax is longer :

Functions<double>::A();
