The lowerer kept the tuple bindings that are only forwarded in one map for the whole program, keyed by local id. Local ids are unique within one function only: two wrappers that both bind `arguments` (or a `const args = arguments as any` alias) declare the same id, so a wrapper whose tuple exists found the other wrapper's entry, and reading an element of its `arguments` failed with "forwarded-only 'arguments' read as a value". Each function's context now keeps its own map. The corpus program wraps functions with a forwarding-only wrapper and with one that also reads an element of `arguments`, directly and through an alias, in both orders.
