Joe

Joe is a concise language derived from J and is designed for code golfing. So, if you're familiar with J, you can easily grasp Joe. Otherwise, let me run through the most important points:

• Joe is not a von Neumann -language
• Functions can usually implicitly handle arbitrarily nested lists (arrays).
  • 1+1 2 3 is 2 3 4
  • 1 2 3+1 2 3 is 2 4 6
• Functions are usually defined in tacit-style, which is closely related to pointless style.

Note: The interpreter uses the Arpeggio module to parse code. You can install it by executing pip install arpeggio.
