PHP syntax error

Hi,
We use wpengine. They have git repos built in as part of their service. When you push to a wpengine repo, it performs a syntax check on all php files being pushed. If any file fails the syntax check, wpengine quits the push process. I get the following errors when pushing the Awesome Support plugin and the Awesome Support: E-Mail Support plugins

PHP Parse error: syntax error, unexpected ‘.’, expecting ‘)’ in – on line 10
remote: – warning: syntax Error Found in wp-content/plugins/awesome-support/vendor/composer/autoload_static.php …

PHP Parse error: syntax error, unexpected ‘.’, expecting ‘)’ in – on line 10
remote: – warning: syntax Error Found in wp-content/plugins/awesome-support-email-support/vendor/composer/autoload_static.php …

Looks like a problem with the way the magic constant __DIR__ is being used, here is a stackoverflow question about it

This is preventing us from being able to use versioning for our site, any help would be greatly appreciated.

Thanks!
