[Moose-dev] Re: PetitParser, same character multiple times

As far as I understand, you would want something that parses any of the following: "aa" "bb" "cc" "dd" The simplest way would be something like: ($a asParser , $a asParser) / ($b asParser , $b asParser) ... The problem is that this will result in many objects and redundant checks. I think I would implement it as a specialization of PPPredicateSequenceParser in which you store the first element, and add the extra condition that any of the following elements must be the same.
