The assignment arrow ← defines a new variable in a block, while ↩ modifies an existing one.

BQN uses the ligature character ‿ for stranding, instead of plain juxtaposition. It also has a list notation using ⟨⟩, and [] for higher-rank arrays.

Here are some closest equivalents in Dyalog APL for the BQN functions that don't use the same glyphs. Correspondence can be approximate, and ⌽ is just used as a decorator to mean "reverse some things".

+

Glyphs +-×÷⌊⌈|⊣⊢⌽⍉ have nearly the same meaning in BQN as APL. Closest equivalents in Dyalog APL for the other functions are below (except !, Assert).
