Like http://en.wikipedia.org/wiki/ML_%28programming_language%29 ?

Oh, didn't know about this one
http://en.wikipedia.org/wiki/Miranda_%28programming_language%29

Using asSet is taking the risk of loosing class information because of

printStringLimitedTo: limit
       "Answer a String whose characters are a description of the receiver.
       If you want to print without a character limit, use fullPrintString."
       | limitedString |
       limitedString := String streamContents: [:s | self printOn: s]
limitedTo: limit.
       limitedString size < limit ifTrue: [^ limitedString].
       ^ limitedString , '...etc...'
