In this RubyFringe talk, Reginald Braithwaite shows how to write Ruby that reads, writes, and rewrites Ruby. The demos include extending the Ruby language with conditional expressions, new forms of evaluation such as call-by-name and call-by-need, and more.
Reginald Braithwaite was the tech lead on the team that created JProbe Threadalyzer, a tool that did automatic detection of potential threading-related bugs. Shortly after that he became Program Manager for the suite of JProbe tools and then Development Manager. He is a speaker at conferences like RubyFringe and MeshU. He is author of the Invocation Construction Kit and Rewrite for Ruby.
RubyFringe is an avant-garde conference for developers that are excited about emerging Ruby projects and technologies. They're mounting a unique and eccentric gathering of the people and projects that are driving things forward in our community.
