I have updated the Lua grammar to resolve the following issues:

  • Resolve errors related to mutually left-recursive rules. This is apparent when you try to convert nautilus grammars to antlr grammars, as done in Grammar-Mutator.
  • Allow function calls in statements.
  • Correct one function definition rule.

These changes align with the official Lua grammar.
