TLDI '09 24 January 2009 (Saturday)


The role of types and proofs in all aspects of language design, compiler construction, and software development has expanded greatly in recent years. Type systems, type analyses, and formal deduction have led to new concepts in compilation techniques for modern programming languages, verification of safety and security properties of programs, program transformation and optimization, and many other areas. In light of this expanding role of types, the ACM SIGPLAN Workshop on Types in Language Design and Implementation (TLDI' 09) follows six previous International Workshops on types in compilation and language design (TIC '97, TIC '98, TIC '00, TLDI '03, TLDI '05, and TLDI '07), with the hope of bringing together researchers to share new ideas and results in this area.

Submissions for this event are invited on all interactions of types with language design, implementation, and programming methodology. This includes both practical applications and theoretical aspects. TLDI '09 specifically encourages papers from a broad field of programming language and compiler researchers, including those working in object-oriented, dynamically-typed, late-binding, systems programming, and mobile-code paradigms, as well as traditional fully-static type systems. Topics of interest include:

This is not meant to be an exhaustive list; papers on novel utilizations of type information are welcome. Authors concerned about the suitability of a topic are encouraged to inquire via electronic mail to the program chair prior to submission.

Submission Guidelines

Authors should submit a full paper of no more than 12 pages (including bibliography and appendices) by Wednesday, October 8, 2008 5PM EDT Thursday, October 9, 2008 5PM Eastern Daylight Savings Time. The submission deadline and length limitations are firm. Submissions that do not meet these guidelines will not be considered.

All submissions should be in standard ACM SIGPLAN conference format: two columns, nine-point font on a ten-point baseline. Detailed formatting guidelines are available on the SIGPLAN Author Information page, along with a LaTeX class file and template.

Papers must be submitted in Adobe Portable Document Format (PDF) and must be formatted for US Letter size (8.5"x11") paper. Authors for whom this is a hardship should contact the program chair before the deadline.

Submitted papers must adhere to the SIGPLAN Republication Policy. Submissions should contain original research not published or submitted for publication elsewhere.
