Magento HHVM Module Compatibility

What is this?

This is a standard Magento installation that I use for testing popular module's compatibility with Magento:

Modules and their versions are managed through composer.
Modules are picked by their popularity, though due to this repository being public there will be no paid extensions.

- Currently contains an issue where HHVM cannot properly decode a SOAP request.

Please test my module too?

Modify composer.json to add your module as a dependency.
Ensure that your module cleanly installs and doesn't add any rewrite conflicts.
Create a pull request.

How do you find the time to do this?

Byte Internet has been nice enough to provide a list of most popular repositories and are sponsoring some of my work on HHVM.
