If you're currently using this project, you may want to check out the successor https://github.com/reactphp/async instead 🎉 We've merged the await() function from this project into the new react/async package without the optional parameters $loop and $timeout. Upgrading should still be simple and should take no longer than a few minutes in most cases:

// old
$result = Clue\React\Block\await($promise);

// new
$result = React\Async\await($promise);

This project may see some smaller adjustments / fixes in the future, but all development efforts and new features will focus on react/async instead. Upgrading is highly recommended.

We're planning to soft-deprecate this project in the future after a reasonable transition period. We want to ensure a smooth upgrade path and will not break any existing implementations, so you can keep installing old versions from this project, but should not expect any major changes and feature additions.
