Stefan Marr I am working at the School of Computing at the University of Kent. My work focuses on programming language implementation techniques, complex concurrent systems, and tooling.

Much of work revolves around making interpreters faster, detecting and preventing concurrency bugs at run time, and use modern language runtime systems to provide programmers with better tooling.

Feb 18, 2008: Traits for PHP

During the last six months I’ve studied a language construct called Traits. It is a construct enabling fine-grained code reuse beside single inheritance in classical object oriented languages.
