Terms are defined in a [BNF](https://en.wikipedia. 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 `ยท`, or `๐จ` in a monadic brace function, can be used as statements but not expressions. +A program is a list of statements.
