Scheme has long served as a vibrant platform for exploring programming-language ideas and advancing programming-language concepts. From contracts to macros and from continuations to growing languages, it is a dynamic environment for reconceptualizing how we program.

In this keynote, I present several underexplored language-design directions that hold significant potential. Due to Scheme’s rich history and design, it is uniquely positioned to lead the development of these ideas. For example, supporting more sophisticated continuation structures and more expressive macro systems. These directions point to new frontiers where we can push the boundaries of how programs are structured and how we think about programming.
