repeat, stop_when, timeout, etc. (not all proposed yet) • A standard set of abstractions (aka, concepts) derived from the algorithms • Efficient interoperability with coroutines • An open and extensible system execution context, nursery for spawned work4 P2300: STD::EXECUTION Proposes: • A set of concepts that represent: • A handle to a compute resource (aka, scheduler) • A unit of lazy async work auto [a, b, c] = std::this_thread::sync_wait( std::move(work) ).value(); } P2300 proposes these concepts and algorithms, among others.8 EXAMPLE: LAUNCHING CONCURRENT WORK Use pipe syntax if you want
