Dzaima/BQN

dzaima/BQN is an independent implementation of BQN in Java by Stack Exchange user dzaima, created by modifying the source of dzaima/APL. While dzaima/APL adds significant new functionality and is different from any other APL, dzaima/BQN follows the BQN specification closely and extends it with system functions.

dzaima/BQN has often been the first implementation to support new functionality, particularly syntax such as block headers, and is much faster than the self-hosted BQN implementation. Its bytecode format was adopted by that implementation BQN, and, since it can compile and run BQN sources, it has also been used for development and bootstrapping.
