Although the core language primitives (also known as squiggles) are closest to our hearts, we spend a lot of time creating interfaces to external components such as the operating system, widely-used APIs, and file and data formats. The core language remains stable with occasional extensions, but the system functions that provide these interfaces need constant enhancements as the world evolves around us.
