Yeah, that's also the main reason why I didn't submit anything to LambdaDays! It's about time to drink some Java developer's blood again 🍷😂

My talk about "Shoehorning DI into a FP language" at LambaConf is now available: www.youtube.com/watch?v=_AuF.... Now for the reveal... This approach doesn't scale and I did not realize at the time. Wait for my updated talk at LambdaDays 2025 to discover a much better approach!
