| /// @assertion The grammar is: |
| /// |
| /// // Existing rules: |
| /// type ::= functionType '?'? // Existing production. |
| /// | recordType // New production. |
| /// | typeNotFunction // Existing production. |
| /// |
| /// typeNotFunction ::= 'void' // Existing production. |
| /// | recordType // New production. |
| /// | typeNotVoidNotFunction // Existing production. |
| /// |
| /// // New rules: |
| /// recordType ::= '(' recordTypeFields ',' recordTypeNamedFields ')' |
| /// | '(' recordTypeFields ','? ')' |
| /// | '(' recordTypeNamedFields ')' |
| /// |
| /// recordTypeFields ::= recordTypeField ( ',' recordTypeField )* |
| /// recordTypeField ::= metadata type identifier? |
| /// |
| /// recordTypeNamedFields ::= '{' recordTypeNamedField |
| /// ( ',' recordTypeNamedField )* ','? '}' |
| /// recordTypeNamedField ::= type identifier |
| /// recordTypeNamedField ::= metadata typedIdentifier |
| /// |
| /// The grammar is exactly the same as parameterTypeList in function types but |
| /// without `()`, `required`, and optional positional parameters since those |
| /// don't apply to record types. A record type can't appear in an extends, |
| /// implements, with, or mixin on clause, which is enforced by being a |
| /// production in `type` and not `typeNotVoid`. |
| /// |
| /// @description Checks that it is a compile-time error if `var` keyword is used |
| /// instead of type |
