Interface for token descriptions This doe snot define an interface for token descriptions but rather defines a type for token description, that will then be used by others interfaces.
type descr = {
article : string;
kind : string;
lexeme : string;
hint : string option;
}
The description fo a token, to be used when pretty-printing error messages. The idea is to be able to ouput a message such as "the parser expetced something, but got %article %kind: '%lexeme'"
