General Updates

New Solver

  • Fix many crashes (thanks you for your bug reports!)
  • Type functions can now call each other
  • Type functions all evaluate in a single VM. This should improve typechecking performance and reduce memory use.
  • export type function is now forbidden and fails with a clear error message
  • Type functions that access locals in the surrounding environment are now properly a parse error
  • You can now use :setindexer(types.never, types.never) to delete an indexer from a table type.
