The 16th Dynamic Languages Symposium (DLS) at SPLASH 2020 is the premier forum for researchers and practitioners to share research and experience on all aspects on dynamic languages.

DLS 2020 invites high quality papers reporting original research and experience related to the design, implementation, and applications of dynamic languages. Areas of interest include, but are not limited to,

- innovative language features - innovative implementation techniques - innovative applications - development environments and tools - experience reports and case studies - domain-oriented programming - late binding, dynamic composition, and run-time adaptation - reflection and metaprogramming - software evolution - language symbiosis and multi-paradigm languages - dynamic optimization - interpretation - just-in-time and ahead-of-time compilation - soft/optional/gradual typing - hardware support - educational approaches and perspectives - semantics of dynamic languages - frameworks and languages for the Cloud and the IoT

Submission Details ------------------

Submissions must neither be previously published nor under review at other events. DLS 2020 uses a lightweight double-blind, two-phase reviewing process.

Papers are assumed to be in one of the following categories:

**Research Papers:** describe work that advances the current state of the art

**Experience Papers:** describe insights gained from substantive practical applications that should be of a broad interest

**Dynamic Pearls:** describe a known idea in an appealing way to remind the community and capture a reader’s interest

The program committee will evaluate each paper based on its relevance, significance, clarity, and originality. The paper category needs to be indicated during submission, and papers are judged accordingly.

Papers are to be [submitted electronically](https://dls20.hotcrp.com/) in PDF format. Submissions must be in the ACM SIGPLAN conference acmart format, 10 point font, and should not exceed 12 pages. Please see full details in the instructions for authors available at:

https://conf.researchr.org/home/dls-2020#Instructions-for-Authors

DLS 2020 will run a two-phase reviewing process to help authors make their final papers the best that they can be. Accepted papers will be published in the ACM Digital Library and will be freely available for one month, starting two weeks before the event.
