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 ]

Thanks to both of you for the suggestions, now the keyword parser (and similarly the separator) is implemented using:

keywordParsers := keywords keysSortedSafely collect: [:eachKey | keywords at: eachKey ].

^ (keywordParsers reduce: [ :a :b | a / b ]) token trimBlanks

Since I already have a dictionary "keywords" with each keyword as a key, and the corresponding parser (not tokenized) as a value.

This looks better.

Should these parsers be caseInsensitive? I thought keywords are case sensitive. Maybe that was another story?

The Java keywords are not caseInsensitive :). I was talking about other situations when you might need that.

Cheers, Doru
