Add a new `each` method to the Sequence class in the Wren programming language, allowing iteration over sequence elements by passing each element to a provided function. This replaces the previous pattern of using `map` with `Fiber.yield` in examples, providing a more direct and idiomatic way to perform side effects per element. The implementation includes a core library method in `core.wren`, a C source string in `wren_core.c`, documentation in the Sequence markdown file, and three test cases covering normal iteration, empty sequences, and non-function argument error handling.
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 inwren_core.corwren_value.c, it will most likely break one of these tests. -
io/- Tests for the built in IO library. In other words, methods on theIOclass. If a bug is inwren_io.c, it should break one of these tests. -
language/- Tests of the language itself, its grammar and runtime semantics. If a bug is inwren_compiler.corwren_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.
