Additional Lexical Specifications

Additional keywords and identifiers.

_cast

Used to cast an expression or a l-value to a given type.

_chunks, _exp, _lvalue, _namety

These keywords are used to plug an existing AST into an AST being built by the parser. There is a keyword per type of pluggable AST (list of declarations, expression, l-value, type name).

Reserved identifiers

They start with an underscore, and use the same letters as standard identifiers. These symbols are used internally by the compiler to name or rename entities. Note that :code:`_main` is still a valid identifier, not a reserved one.

reserved-id = "_" { letter | digit | "_" }
