The #IFL23 , the The 35th Symposium on Implementation and Application of Functional Languages, has published their Call for Papers.
The symposium is in Braga, Portugal, end of August. Draft paper submission deadline is July 31st.
There is no mention on the website of a @The Public Health Pledge , a #CodeOfConduct or other measures to keep participants healthy and safe, physically or otherwise, so that's something to keep in mind before applying.
