Global Primitives:

• Go
• Register
• Host API:
  • Do
  • Log

Main script Primitives:

• Args
• Data
• Connect

Good to have:

• Compile modules before startup to validate modules are ok
• "Prerun" the modules to track module dependencies and validate all dependencies are met
• Detailed logging from connection success/failures and module use from lowest to highest (with results)
• Module stack trace?
