  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.

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

Ciao,
