Passing method references to high-order functions

I would like to pass a reference to a method once the object has been instanciated to a high-order function as an argument, but it seems not supported, right?
Example:

@value
struct Foo:
    fn func(self) -> Int:
        return 42

# None of these declarations work:
fn high_order_func(f: fn (Foo) -> Int) -> Int:
# fn high_order_func(f: fn () -> Int) -> Int:
    return f()

fn main() -> Int:
    foo = Foo()
    print(high_order_func(foo.func))

@value
struct Foo:
    fn func(self) -> Int:
        return 42

# None of these declarations work:
fn high_order_func(f: fn (Foo) -> Int) -> Int:
# fn high_order_func(f: fn () -> Int) -> Int:
    return f()

fn main() -> Int:
    foo = Foo()
    print(high_order_func(foo.func))
