The 2021 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 26 June 2021.
Authors will be notified by 12 July 2021.
Camera-ready versions are due 21 July 2021.
All deadlines are (23:59 UTC-12), “Anywhere on Earth”.
Workshop will be held online 27 August 2021, 11:00--19:30 UTC

Submission Information

Paper submissions must use the format acmart and its sub-format sigplan acmsmall (note the change from last year). 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:

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 expected to be 10–24 pages in length using the single-column SIGPLAN acmart style. (For reference, this is about 5–12 pages of the older SIGPLAN 2-column 9pt style.) Abstracts submitted for lightning talks should be 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 published as a Technical Report at Northeastern University and uploaded to

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.
Reviewing Process

Scheme 2021 will use lightweight-double-blind reviewing. Submitted papers must omit author names and institutions and reference the authors’ own related work in the third person (e.g., not “we build on our previous work…” but rather “we build on the work of...”).

The purpose is to help the reviewers come to an initial judgement about the paper without bias, not to make it impossible for them to discover the authors if they were to try. Nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult (e.g., important background references should not be omitted or anonymized).
Formatting Information

Full papers and experience reports should use the sigplan acmsmall option to acmart.
Lightning talks can be submitted as either a text file or a PDF file.
It is recommended to use the anonymous and review options to acmart when submitting a paper; these options hide the author names and enable line numbers for easy reference in review.

> Submission deadline is 26 June 2021.

That's tomorrow.

The website says, in the Submission Link section:

"We will post the submission link closer to the deadline."

How much closer to the deadline do you want to get? :)

We're adhering to the time-honored Scheme Workshop tradition of being last minute!

The link is now live. *And* we extended the deadline by one week, at the request of several potential authors:
