Max Horvath has called for some help in getting a feature included (and fully working) into the next release of the Eclipse PDT extension - phar support.
With Eclipse PDT 2.0 to be released in September (or October) support for namespaces is already on the roadmap. Support for Phar archives has not been listed, yet. But in my opinion Eclipse PDT 2.0 must support handling Phar archives when PHP 5.3 will hit the street.
He points out some of the current lackings that the Eclipse extension has including the inability to browse phar archives and that there is no way to debug the archives. He's opened a feature request for the functonality to be added and suggested fleshing it out on the wiki.
This is where you come in - he wants to know what sort of support that developers out there would like for phar in this next release. Just leave comments on his blog with your ideas.
