Module Grammar.Unsafe

module Unsafe: sig  end
Module for clearing grammars and entries. To be manipulated with care, because: 1) reinitializing a grammar destroys all tokens and there may have problems with the associated lexer if it has a notion of keywords; 2) clearing an entry does not destroy the tokens used only by itself.

val gram_reinit : Grammar.g -> Token.t Token.glexer -> unit
