the following code (from README, use with boostext::di) does not compile (clang 17, gcc 11)

#include <boost/di.hpp>
#include <boost/te.hpp>
#include <iostream>

namespace te = boost::te;
namespace di = boost::di;

struct Drawable : te::poly<Drawable> {
  using te::poly<Drawable>::poly;

  void draw(std::ostream &out) const {
    te::call([](auto const &self, auto &out) { self.draw(out); }, *this, out);
  }
};

struct Rect {
  void draw(std::ostream &out) const { out << "Rect" << std::endl; }
};

struct Circle {
  void draw(std::ostream &out) const { out << "Circle" << std::endl; }
};

class Example {
public:
  Example(Drawable const drawable, std::ostream &out)
      : drawable{drawable}, out{out} {}

  void draw() { drawable.draw(out); }

private:
  Drawable const drawable;
  std::ostream &out;

int main() {
  const auto injector = di::make_injector(di::bind<Drawable>.to<Circle>(),
                                          di::bind<std::ostream>.to(std::cout));

  injector.create<Example>().draw(); // prints Circle
}
