* Implementations for operators and async functions on AsyncSequence per SE-0298 * Add trailing new lines to AsyncSequence adopter files * Remove extra // from preambles * Transition sequence properties and sequence initializers to internal * Rename Upstream to Base * Rename "Failable" asynchronous sequences to "Throwing" * Make iteration consistent with closure lifetimes and track failure via state * Use for await syntax for async function extensions on AsyncSequence * Work-around rethrows calculations being incorrect for conformance + closure rethrowing * Update testing names to reflect Throwing versus Failable * Incorperate runAsyncAndBlock into the test function for suite calls * Remove @frozen from AsyncSequence operators * Back out reduce family functions for now due to IRGen bug * Additional corrections for throwing cases and fix up potential linux crasher * Add a upstream and throwing tests and correct flatMap's throwing behavior * Unify parameter names to count * Add a more helpful precondition on prefix * Add tests for throwing cases of non closure async functions on AsyncSequence * Correct missing count transition in dropFirst * Correct missing , in assertion * [NFC] add commentary on optimization in dropFirst on dropFirst * Disable collect tests for non macOS platforms for now * Disable all async sequence tests for non macOS platforms for now
