[edit] Modtalk

  1. Build program
  2. Analyze program
    • Semantic analyzer
    • Definition installer
    • Module migrator (makes sure changes are still sound; returns an instance of MigrationResult)
  3. Load program with no methods into environment
    • Instantiate classes
    Must embed in Squeak namespace (proper embedding)
