A meta language toolchain to build systems rapidly

Reason: Build Systems Rapidly

• Approachable syntax.
• Powerful, automatic source code formatting.
• Adopt incrementally with JavaScript/C interop.
• Ahead-of-time compilation to assembly - without a language level VM.
• Rapidly develop and share projects.
