BQN's built-in operations also have patterns to indicate the syntactic role: 1-modifiers (˜¨˘⁼⌜´`) are all superscript characters, and 2-modifiers (∘○⊸⟜⌾⊘◶⚇⎉⍟) all have an unbroken circle (two functions ⌽⍉ have broken circles with lines through them). Every other built-in constant is a function, although the special symbols ¯, ∞, and π are used as part of numeric literal notation.

Assignment

-

Another element that can be included in expressions is assignment, which is written with ← to define (also called "declare" in many other languages) a variable and ↩ to change its definition. A variable can only be defined once within a scope, and can only be changed if it has already been defined. However, it can be shadowed, meaning that it is defined again in an inner scope even though it has a definition in an outer scope already.

Separators

 
The characters ⋄ and , and newline are completely interchangeable and are used to separate expressions. An expression might be an element in a list or a line in a function. Empty sections—those that consist only of whitespace—are ignored. This means that any number of separators can be used between expressions, and that leading and trailing separators are also allowed. The expressions are evaluated in text order: left to right and top to bottom.

 
List notation

Full documentation

 
Lists (1-dimensional arrays) are enclosed in angle brackets ⟨⟩, with the results of the expressions in between being the list's elements. Lists of two elements or more can also be written with the ligature character ‿. This character has higher binding strength than any part of an expression. If one of the elements is a compound expression, then it will need to be enclosed in parentheses.
