I think this parser is called PPFailingParser. It is useful to
generate custom error messages. It always fails without consuming
anything.
However for the given example I would use
keywords reduce: [ :a :b | a asParser / b asParser ]
for a shorter and more performant implementation.

Hi,
I went quickly through the PetitJava implementation and I stumbled across the keywords
implementation. I would propose a simpler solution:
keyword
^ (arrayOfKeywords inject: PPEpsilonParser new not into: [:p :key | p / key
asParser ]) token trimBlanks .
Now the question is if it makes sense to have a separate parser class equivalent to
PPEpsilonParser new not. If yes, what would a good name be?
Cheers,
Doru
