Remove "(bob)" author prefix from all TODO comments in benchmark/method_call.wren, include/wren.h, src/main.c, src/wren_common.h, src/wren_compiler.c, src/wren_core.c, src/wren_value.c, src/wren_value.h, and src/wren_vm.c. Update the TODO_PATTERN regex in metrics script to match the new format without author parentheses. Also refactor test file counting in metrics to use os.walk with fnmatch for recursive directory traversal instead of glob.iglob.
When a class is defined, its superclass is not known until runtime since class definitions are imperative statements. This adds a new wrenBindMethod function that walks the bytecode of a method after it is bound to a class, adjusting LOAD_FIELD/STORE_FIELD indices to account for inherited fields and patching superclass dispatch targets. The newClass function now correctly accumulates numFields from the superclass chain, and the VM calls wrenBindMethod when binding methods to a class. Includes new test files for inherited field access and the is operator.
Move equality and inequality primitives from Bool and Function to a single Object-level implementation using valuesEqual, and add wrenGetClass to return the runtime class of any value. Refactor newSingleClass to inherit methods from superclass and wire metaclass superclass to classClass. Add type-checking tests for all built-in types and class inheritance.
Add TOKEN_IS token and CODE_IS bytecode to support runtime type checking via the `is` keyword. Refactor primitive registration by replacing `registerPrimitives` with `loadCore`, which compiles a core library string to define built-in classes (Bool, Class, Function, Num, Null, String, IO) and then attaches primitive methods to them. Update Primitive typedef to remove unused numArgs parameter, and add findGlobal helper to retrieve globals by name. Include test files for class syntax, class instantiation, and the new `is` operator.
