This is a small demo of how X lists can implement reflection in CPP. The demo implements a pretty printer for structs.

To build, run make, this will generate an executable reflection. Running it should print out:

f: Foo {
  x: 0
  y: hi
  z: 5.400000
}
b: Bar {
  foo: Foo {
    x: 6
    y: bar foo
    z: 11.700000
  }
  asdf: 10
}
