The zero-argument overload of `join` on `Sequence` was previously defined as a
getter-style method without parentheses. This change makes it a regular method
that requires explicit parentheses, consistent with the one-argument `join(sep)`
variant and standard Wren method syntax. The implementation now reads
`join() { join("") }` instead of `join { join("") }`.
All call sites in tests and documentation are updated accordingly.
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. -
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.
