TLDI 2011


The Sixth ACM SIGPLAN Workshop on

Types in Language Design and Implementation


Austin, Texas, USA

Tuesday, January 25, 2011

To be held in conjunction with POPL 2011




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-based analyses and type-theoretic deductive systems have been central to advances in compilation techniques for modern programming languages, verification of safety and security properties of programs, program transformation and optimization, and many other areas. The ACM SIGPLAN Workshop on Types in Language Design and Implementation brings researchers together to share new ideas and results concerning all aspects of types and programming, and is now an annual event. TLDI 2011 is the sixth workshop in the series and will be co-located with POPL in Austin, Texas in January 2011.

Submissions for TLDI 2011 are invited on all interactions of types with language design, implementation, and programming methodology. This includes both practical applications and theoretical aspects. TLDI 2011 specifically encourages papers from a broad field of programming language and compiler researchers, including those working on object-oriented or dynamic languages, systems programming, mobile-code or security, 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 Monday, October 11, 2010. 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 electronically via the workshop website 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.


As in previous years, accepted papers will be published by the ACM and appear in the ACM digital library. A printed proceedings will be available at the workshop.
