The Workshop on Gradual Typing (WGT) aims at disseminating the latest results on the integration of compile-time and run-time checking of program invariants, such as the integration of static and dynamic type checking. The workshop serves as an incubator for ideas, open problems, and manuscripts: it is a place where the community can meet, discuss, and give each other constructive feedback. The workshop will encourage participation from researchers in both academia and industry, drawing people from the many active projects on both sides of the aisle.
Format: A one-day workshop with 1-2 invited talks and 6-9 regular talks. The submission formats will be fullpapers (max 25 pages) and short papers (max 10 pages), but there will be no official proceedings. Authors are encouraged to submit polished versions of their workshop submissions to other ACM conferences. The review process is standard, with at least three reviews of each paper by the program committee, who will then select the papers that will be presented at the workshop. The criteria for selection will prioritize novelty and timeliness over presentation quality. The program committee will also decide on the invited talks.
History: This will be the first edition of the Workshop on Gradual Typing. There was a closely related workshop that ran from 2009 to 2016, the Scripts to Programs Workshop (STOP), that was affiliated with the ECOOP conference. With the ending of that workshop coupled with the recent strength of publishing on gradual typing at the ACM SIGPLAN conferences, it seemed that the time was right to start a SIGPLAN affiliated workshop on gradual typing. In that respect, POPL is the right venue to hold this workshop. There have been 12 papers on gradual typing published in the last four editions of POPL and there was a session dedicated to gradual typing in three of the last four editions of POPL.

Call for Papers
First ACM SIGPLAN Workshop on Gradual Typing (WGT) to be held on January 25th, 2020 in New Orleans co-hosted with POPL.
- (Extended) Submission deadline: Sunday, October 27, 2019
- Notification: Sunday, December the 1st, 2019
- Workshop: Saturday, January the 25th, 2020
The ACM SIGPLAN Workshop on Gradual Typing is a venue for disseminating the latest results on the integration of compile-time and run-time checking of program invariants, such as the integration of static and dynamic type checking. The workshop serves as an incubator for ideas, open problems, and manuscripts: it is a place where the community can meet, discuss, and give each other constructive feedback. The workshop will encourage participation from researchers in both academia and industry, drawing people from the many active projects on both sides of the aisle.
We expect the workshop to be informal since its goals are to exchange information, foster collaboration, and establish common ground. This is why not only new results, but also unfinished work with stimulating ideas, or visionary work proposing new research tracks will be welcome. The Program Committee will thus prioritize novelty and timeliness over presentation quality. We also expect authors to use the workshop as a testbed for their work before submitting a polished version of it to mainstream ACM conferences. Thus, the proceedings will not be a formal or archival publication but they will be made available online right before the workshop.
Submission site: http://wgt20.hotcrp.com
Authors are invited to submit unpublished manuscripts using the site above. Submissions must be in pdf and have no more than 25 pages of text, excluding bibliography, using the new ACM Proceedings format for PACMPL. However, we hope to receive also much shorter submissions typically of 5-10 pages. Why such a stark difference in lengths? We think that 5-10 pages are all you need to expose your unbaked topic or your brilliant idea you want present at the workshop, but we do not want authors of a polished work to be obliged to cut their article just for presenting their results at WGT.
PACMPL templates for Microsoft Word and LaTeX can be found at the SIGPLAN author information page. In particular, authors using LaTeX should use the acmart-pacmpl-template.tex file (with the acmsmall option).
Submitted papers must adhere to the SIGPLAN Republication Policy and the ACM Policy on Plagiarism. Concurrent submissions to other conferences, workshops, journals, or similar forums of publication are not allowed.
