A community for those who want to learn and use the APL array programming language. The most current and maintained open-source variant being: GNU APL

This community leans toward the POSIX APL/2 standard; APL has many newer dialects which, while powerful and innovative, are not available as open implementations and may not be officially considered standard APL, per se.

Those who wish to discuss tacit programming and other syntax constructs outside and beyond that of the APL/2 standard may wish to visit the Dyalog corporation’s own website, forums and documentation as their commercial variant diverges from that of APL/2; or the APL Orchard on StackExchange.

That said, however, talk of ‘child’ languages such as: J, K, Q, BQN and so on are by no means discouraged!
