Bob Nystrom eba4911485 fix: error when class inherits from null instead of defaulting to Object
Previously, inheriting from null would silently fall back to Object superclass. Now validates superclass and raises runtime error if null is provided. Refactored defineClass to remove implicit null-to-Object fallback, added loadCoreVariable helper for module-level core imports, and updated CLASS/FOREIGN_CLASS opcode comments to reflect that null is no longer a valid superclass. Added test case for inherit_from_null.

This contains the automated validation suite for the VM and built-in libraries.

  • benchmark/ - Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself.

  • core/ - Tests for the built in core library, mainly methods on the core classes. If a bug is in wren_core.c or wren_value.c, it will most likely break one of these tests.

  • io/ - Tests for the built in IO library. In other words, methods on the IO class. If a bug is in wren_io.c, it should break one of these tests.

  • language/ - Tests of the language itself, its grammar and runtime semantics. If a bug is in wren_compiler.c or wren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes.

  • limit/ - Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
