Hello, Thank you for your attention, and my apologies for any duplication you receive. Please find below the Call for Papers for the *2020 Scheme and Functional Programming Workshop*. The deadline has been extended to *May 31*. Please also note that the workshop is now to be held *virtual*ly; hopefully the silver lining is more and wider participation. We look forward to your submissions. *Call for Papers*The 2020 Scheme and Functional Programming Workshop is calling for submissions. We invite high-quality papers about novel research results, lessons learned from practical experience in industrial or educational setting, and even new insights on old ideas. We welcome and encourage submissions that apply to any language that can be considered Scheme: from strict subsets of RnRS to other “Scheme” implementations, to Racket, to Lisp dialects including Clojure, Emacs Lisp, Common Lisp, to functional languages with continuations and/or macros (or extended to have them) such as Dylan, ECMAScript, Hop, Lua, Scala, Rust, etc. The elegance of the paper and the relevance of its topic to the interests of Schemers will matter more than the surface syntax of the examples used. Topics of interest include (but are not limited to): Interaction: program-development environments, debugging, testing, refactoring Implementation: interpreters, compilers, tools, garbage collectors, benchmarks Extension: macros, hygiene, domain-specific languages, reflection, and how such extension affects interaction. Expression: control, modularity, ad hoc and parametric polymorphism, types, aspects, ownership models, concurrency, distribution, parallelism, non-determinism, probabilism, and other programming paradigms Integration: build tools, deployment, interoperation with other languages and systems Formal semantics: Theory, analyses and transformations, partial evaluation Human Factors: Past, present and future history, evolution and sociology of the language Scheme, its standard and its dialects Education: approaches, experiences, curricula Applications: industrial uses of Scheme Scheme pearls: elegant, instructive uses of Scheme *Important dates*Submission deadline is 31 May 2020. Authors will be notified by 12 June 2020. Camera-ready versions are due 30 June 2020. All deadlines are (23:59 UTC-12), “Anywhere on Earth”. Submission Information Paper submissions must use the format acmart and its sub-format acmlarge. They must be in PDF, printable in black and white on US Letter size. Microsoft Word and LaTeX templates for this format are available at: http://www.sigplan.org/Resources/Author/ <https://jason-hemann-dot-yamm-track.appspot.com/Redirect?ukey=1vGxf_aAa6hTH4R869JvZxA5b1cHrErl1gEjXVr1AStE-0&key=YAMMID-93219631&link=http%3A%2F%2Fwww.sigplan.org%2FResources%2FAuthor%2F> This format is in line with ACM conferences (such as ICFP with which we are colocated). It is recommended to use the review option when submitting a paper; this option enables line numbers for easy reference in reviews. We want to encourage all kinds of submissions, including full papers, experience reports and lightning talks. Papers and experience reports are limited to 14 pages, but we encourage submitting smaller papers. Lightning talks are limited to 192 words. Each accepted paper and report will be presented by its authors in a 25 minute slot including Q&A. Each accepted lightning talk will be presented by its authors in a 5 minute slot, followed by 5 minutes of Q&A. The size limits above exclude references and any optional appendices. There are no size limits on appendices, but the papers should stand without the need to read them, and reviewers are not required to read them. Authors are encouraged to publish any code associated to their papers under an open source license, so that reviewers may try the code and verify the claims. Proceedings will be printed as a Technical Report at the University of Michigan and uploaded to arXiv.org <https://jason-hemann-dot-yamm-track.appspot.com/Redirect?ukey=1vGxf_aAa6hTH4R869JvZxA5b1cHrErl1gEjXVr1AStE-0&key=YAMMID-93219631&link=http%3A%2F%2Farxiv.org%2F> . Publication of a paper at this workshop is not intended to replace conference or journal publication, and does not preclude re-publication of a more complete or finished version of the paper at some later conference or in a journal.
