Passing reference as lvalue/rvalue depending on function signature

Let's say I have some data :

struct Bar {};

I need to wrap a function and feed it with this data.

template<typename F>
void foo(F f) {
    Bar bar;
    f(bar);
}

As you can see in this trivial example:

• bar is not a temporary


• I don't need it after calling f

I want to support multiple function signatures, such as :

foo([](Bar){}); // (1)
foo([](Bar&){}); // (2)
foo([](Bar&&){}); // (3)

However gcc complains :

f(bar); // (3) : cannot bind 'Bar' lvalue to 'Bar&&'
f(std::move(bar)); // (2) : no match for call to ...

How would you do to get both ?
