Specification: BQN grammar

BQN's grammar is given below. Terms are defined in a BNF variant. However, handling special names properly is possible but difficult in BNF, so they are explained in text along with the braced block grammar.

The symbols s, F, _m, and _c_ are identifier tokens with subject, function, 1-modifier, and 2-modifier classes respectively. Similarly, sl, Fl, _ml, and _cl_ refer to literals and primitives of those classes. While names in the BNF here follow the identifier naming scheme, this is informative only: syntactic classes are no longer used after parsing and cannot be inspected in a running program.

A program is a list of statements. Almost all statements are expressions. However, explicit definitions and valueless results stemming from ·, or 𝕨 in a monadic brace function, can be used as statements but not expressions.
