PLDI is a forum where researchers, developers, educators, and practitioners exchange information on the latest practical and experimental work in the design and implementation of programming languages. PLDI seeks original research papers that focus on the design, implementation, development, and use of programming languages. Emphasis is placed on innovative and creative approaches to compile-time and run-time technology; novel language designs and features; and results from implementations.
