I say include it. I use it to create dictionary keys from a head while importing delimited text files.
populateFrom: aReadStream delimitWith: delimiters labels: labelCollection
| numberOfFields newEntry item | data := OrderedCollection new. labels := labelCollection collect: [ :each | each withBlanksTrimmed asCamelCase asSymbol ]. numberOfFields := labels size. [aReadStream atEnd] whileFalse: [ item := (aReadStream nextLine) subStrings: delimiters. newEntry := Dictionary new: numberOfFields. item size > numberOfFields ifTrue: [ self error: ['Number of data elements exeeds expected from labels']]. labels withIndexDo: [:label :index | newEntry at: label put: (item at: index ifAbsent: [nil]). ]. data add: newEntry. ].
