Coroutines: Kotlin Versus
summary
Compares concrete coroutine designs and tradeoffs: Kotlin puts a single suspend keyword in the language but leaves builders like launch/produce/Deferred in a library; channels are modeled after Go and remain partly experimental. Traces Python’s evolution from yield/send/yield from to async/await (3.5), and notes C++’s C++ coroutines TS landed in compilers (clang/MSVC) and leverages LLVM intrinsics so many languages can share an efficient implementation. Claims compiler-generated coroutines often outperform handcrafted state machines and can optimize away multiple resume calls into simple prints.
