BQN

Group

BQN replaces the Key operator from J or Dyalog APL, and many forms of partitioning, with a single (ambivalent) Group function ⊔. This function is somewhat related to the K function = of the same name, but results in an array rather than a dictionary.

The BQN prototype does not implement this function: instead it uses ⊔ for a Group/Key function very similar to {⊂⍵}⌸ in Dyalog APL, and also has a Cut function \. The new BQN Group on numeric arguments (equivalently, rank-1 results) can be defined like this:
