Generator and async generator support

Date: 2026-04-27 Area: runtime

Generator and async generator support. Generator method shorthand (*method() and async *method()) is now part of the default method syntax, while function* and async function* remain behind --compat-function because they use the compatibility-gated function keyword. The interpreter uses resumable generator continuations and the bytecode format reserves a single OP_YIELD opcode; yield* is represented as delegation logic rather than a second opcode. language.md § Generators.
