[NEWS: Extended deadline for draft paper submission, Keynote speakers, Tutorials]

### Scope

The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2025 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming.

### Topics of interest

Topics of interest to IFL include, but are not limited to:

- language concepts
- type systems, type checking, type inferencing
- compilation techniques
- staged compilation
- run-time function specialisation
- run-time code generation
- partial evaluation
- (abstract) interpretation
- meta-programming
- generic programming
- automatic program generation
- array processing
- concurrent/parallel programming
- concurrent/parallel program execution
- embedded systems
- web applications
- (embedded) domain specific languages
- security
- novel memory management techniques
- run-time profiling performance measurements
- debugging and tracing
- virtual/abstract machine architectures
- validation, verification of functional programs
- tools and programming techniques

### Keynote speakers

- Roberto Ierusalimschy 

	Departamento de Informática, PUC-Rio, Río de Janeiro, Brazil

- Iván Pérez 

	NASA Ames Research Center, California, USA

### Tutorials

On September 29 and 30, the two days prior to the symposium, four tutorials will be held:

- Gradual typing
	Éric Tanter, University of Chile, Chile

- Type Based Static Analysis
	Jurriaan Hage, Heriot-Watt University, UK

- Development of dApps in the UTxO model
	TxPipe, Argentina

- TBA


### Peer-review process

Differently from previous editions of IFL, IFL 2025 solicits two kinds of submissions:

* Regular papers (12 pages excluding references)
* Draft papers for presentations ('weak' limit between 5 and 15 pages)

Regular papers will undergo a rigorous review by the program committee, and will be evaluated according to their correctness, novelty, originality, relevance, significance, and clarity. Regular papers can be: accepted for publication in the formal proceedings, accepted for presentation at the symposium or rejected.

Draft papers will be screened to make sure that they are within the scope of IFL, and will be accepted for presentation or rejected accordingly.

We require that at least one of the authors present the work at IFL 2025.

Authors of accepted presentations will be given the opportunity to incorporate the feedback from discussions at the symposium and will be invited to submit a revised full article for the formal post-proceedings after the symposium. The program committee will evaluate these submissions according to their correctness, novelty, originality, relevance, significance, and clarity, and will thereby determine whether the paper is accepted or rejected.

Important note to authors about the new ACM open access publishing model ACM has introduced a new open access publishing model for the International Conference Proceedings Series (ICPS). Authors based at institutions that are not yet part of the ACM Open program and do not qualify for a waiver will be required to pay an article processing charge (APC) to publish their ICPS article in the ACM Digital Library. To determine whether or not an APC will be applicable to your article, please follow the detailed guidance here:

https://www.acm.org/publications/icps/author-guidance.

Further information may be found on the ACM website, as follows:

### Peter Landin Prize

The Peter Landin Prize is awarded to the best paper presented at the symposium every year. The honoured article is selected by the program committee based on the submissions received for the formal review process. The prize carries a cash award equivalent to 150 Euros.
