Bob Nystrom 2dc209e585 feat: add foreign class support with allocation, construct opcodes, and CLI callback wiring
Implement the initial infrastructure for foreign classes in the Wren VM, including new opcodes (FOREIGN_CONSTRUCT, FOREIGN_CLASS), a WrenBindForeignClassFn callback type in the public API, and updated CLI vm.c to store and forward foreign binding callbacks via setForeignCallbacks(). The compiler now tracks whether a class is foreign via a new isForeign flag in ClassCompiler, emits CODE_FOREIGN_CONSTRUCT instead of CODE_CONSTRUCT for foreign class constructors, and errors on field definitions inside foreign classes. The debug dump and opcode header gain entries for the new opcodes, and wrenBindSuperclass handles the -1 numFields sentinel for foreign classes to prevent field inheritance from superclasses.

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.
