Parse error: syntax error, unexpected T_STATIC

From the project page

Don't bother using this module if you're not also going to use http://drupal.org/project/memcache or http://drupal.org/project/redis

Are you using that with 5.2?

Actually while I disagree with the support for 5.2 this feature is only available for PHP 5.5
https://3v4l.org/B0DuC

So in your case I'd suggest upgrading.

I think this is the way we've done this before D8.

This still needs 5.3 for the late binding @see https://secure.php.net/get_called_class

It's a quote from the homepage of this... I didn't write it nor do I maintain this module.

I'm trying to help solve the problem here. 5.2 doesn't have the feature these classes are using so may be ever so hard to fix it for 5.2 but my patch fixes 5.3 up.

Also you'd get much faster site going to php 5.3 or better anyways. @see http://www.lornajane.net/posts/2012/php-5-4-benchmarks

Committed/pushed to 7.1-1.x, thanks!

Shouldn't we also update the project page and indicate the new requirement of PHP version 5.3 or newer?

Thanks @catch. @pc-wurm that wouldn't hurt I don't think. What would be cool is if the project's PHP requirement could be read on to the page automatically on all project pages. But I guess that would be in the drupal.org/infra queues.

Even with this patch, I couldn't get drush rr to complete.
I needed to disable the module, upgrade the files, then enable the module again.
