Code Golf (https://code.golf/) supports unrestricted execution and answer checking for their growing list of problems in #APL (Dyalog APL). APL is listed in the "experimental" section of the supported languages list – once a sufficient number of people have submitted solutions, it will move to the main list of languages and a leaderboard will be added. Please help APL achieve this by exploring the site and submitting APL solutions.
