description: Promise.race rejects if IteratorStep throws
Remove unnecessary ES2015 syntax; add feature flags where appropriate. This allows these tests to be more easily reused to test Promise implementations in isolation.

features: [Symbol.iterator]
Make asynchronous test configuration explicit For asynchronous tests, the contract between test file and test runner is implicit: runners are expected to inspect the source code for references to a global `$DONE` identifier. Promote a more explicit contract between test file and test runner by introducing a new frontmatter "tag", `async`. This brings asynchronous test configuration in-line with other configuration mechanisms and also provides a more natural means of test filtering. The modifications to test files was made programatically using the `grep` and `sed` utilities: $ grep "\$DONE" test/ -r --files-with-match --null | \ xargs -0 sed -i 's/^\(flags:\s*\)\[/\1[async, /g' $ grep "\$DONE" test/ -rl --null | \ xargs -0 grep -E '^flags:' --files-without-match --null | \ xargs -0 sed -i 's/^---\*\//flags: [async]\n---*\//'
