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?
