BQN

BQN is an APL-family language designed primarily by Marshall Lochbaum. Although it maintains the concept of array-driven computing and much of APL's array functionality, BQN discards all compatibility with other array languages and changes many fundamental concepts. It uses the based array model with dedicated array notation, distinguishes between data types and expression roles to give the language a context-free grammar with first-class functions, and uses a new set of glyphs with different primitive pairings. The language uses the leading axis model and tacit programming as core paradigms. Its implementation is largely self-hosted, with an array-based compiler like Co-dfns.

Modifiers
1-modifiers in BQN use superscript symbols, while 2-modifiers use symbols with a circle, but not one with a line through it like  and.

Some modifiers are closely related, and some of their glyphs are intended to allude to this:
 * The three 1-modifers Cells, Each , and Undo are equivalent to using a right-operand of   with the 2-modifiers Rank , Depth , and Repeat . Therefore the 2-modifiers are circled versions of the 1-modifiers (except in the case of Undo/Repeat).
 * Under is in principle equivalent to  . Therefore,   is a combination of the glyphs   and.
