Compilers are the New Frameworks
— Tom Dale
Imagine a world where the robust, mature ecosystems of development tools meet the cutting-edge performance of modern compilers. That's what we're building here — a platform that takes the best of established technologies and infuses them with a new, state-of-the-art compiler.
