Adding repr implementation to print structs

Can you print out a struct like:

@value
struct MyPair:
    var first: Int
    var second: Int

    fn __repr__(self):
        print("first:", self.first)
        print("second:", self.second)

fn main():
    print(MyPair(2, 4))

@value
struct MyPair:
    var first: Int
    var second: Int

    fn __repr__(self):
        print("first:", self.first)
        print("second:", self.second)

fn main():
    print(MyPair(2, 4))

Not yet this is blocked by traits, which are currently being worked on, for now you can create a separate method:

@value
struct MyPair:
    var first: Int
    var second: Int

    fn print_all(self):
        print("first:", self.first)
        print("second:", self.second)


fn main():
    MyPair(2, 4).print_all()

@value
struct MyPair:
    var first: Int
    var second: Int

    fn print_all(self):
        print("first:", self.first)
        print("second:", self.second)


fn main():
    MyPair(2, 4).print_all()
