Rembulan completeness table

Missing language/runtime features

• garbage collection, __gc metamethod
• strings:
  • string library locale support
• tables:
  • weak tables
  • efficient array tables

Standard library

Statuses:

• -- full compatibility: if it doesn't work, it's a bug
• -- partial compatibility, caveats apply
• -- a stub; does not cause an error in most cases, but has no effect
• -- not implemented; an error-throwing stub is present
• -- not implemented; no stub present (will evaluate to nil)
