 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. Valueless results stemming from `·`, or `𝕨` in a monadic brace function, can be used as statements but not expressions.

An extension to BQN to allow first-class namespaces would extend ordinary expressions so that `NS_STMT` would no longer be needed, as it would be a subset of `EXPR`.

 A namespace block is very similar in grammar to an ordinary immediate block, but allows export declarations with `⇐`, either in place of the ordinary definition `←` or in the special `EXPORT` statement. The arrow `⇐` can also be placed in the header to mark a namespace block. Since the block returns all exported values and not the result of the last line, the last line does not need to be an expression.
