Add support for prelexed
+ %type shall be used to match against a lexical type.
+
+ Some languages may require (or at least it would helpful)
+ context handling during parsing. For this, rule should
+ be annotatable to add hooks to the parser, these will be
+ place before the rule name: @open(function-name) should
+ call function-name at the beginning of the rule, and
+ @close(function-name) should call function-name at the
+ end of the rule. When the parser decides that it took
+ the wrong path, it will check if either function has
+ added all callback function for when the node is retracted,
+ and if so call that function. The two former hooks shall
+ also be able to call the parser to commit to the path
+ it's on, which will cause the parser to fall if it needs
+ to backtrack bejoined that point, this will also allow
+ the application to take action on parsed rules and
+ deallocate memory that is no longer needed after that.
+ The hooks shall also be able to cause the parser to abort.
