Scheme 2025

The Scheme and Functional Programming Workshop is a yearly meeting of programming language practitioners who share an aesthetic sense embodied by the Algorithmic Language Scheme: universality through minimalism, and flexibility through rigorous design.

Call for Papers

The 2025 Scheme and Functional Programming Workshop is calling for submissions.

We invite high-quality papers and talk proposals about novel research results, lessons learned from practical experience in an industrial or educational setting, and even new insights on old ideas. We welcome and encourage submissions that apply to any dynamic functional language, especially those that can be considered a 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

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

Submission Information

We welcome the following kinds of submissions.

• Full papers and experience reports: 5-12 pages. Accepted submissions will be included in the proceedings.

• Position papers: 2-4 pages. Authors may choose whether to publish their paper in the proceedings.

• Lightning talks: 1 page. Talk abstracts will not be included in the proceedings.

All submissions should use the new ‘acmart’ format and the two-column ‘sigplan’ subformat (not to be confused with the one-column ‘acmsmall’ subformat). Please use the anonymous and review options to obscure author information and enable line numbers. The page limits do not include references or optional appendices.

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 in the ACM Digital Library.

Please submit papers through the workshop’s HotCRP site.

Lightweight double-blind reviewing

Scheme 2025 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 judgment 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).

Participant Support

Attendees with accepted papers can apply for a SIGPLAN PAC grant to help cover participation-related expenses. PAC also offers other support, such as for child-care expenses during the meeting or for accommodations for members with physical disabilities. For details on the PAC program, see its web page.
