It reminds me of Javascript there you have similar constructs via apply() and i tend to think that the name is not too bad either. #(1 2 3) apply:[:a :b :c | ] I am a bit sceptic about the idea though. Given the examples you provided i do think it’s a neat solution but when i consider: (('2020-03-28' tokensBasedOn: $-) collect: #asNumber) destructDo: [:year :month :day | Date newDay: day monthNumber: month year: year] I’m sure that the input string is not a literal because then this whole code doesn’t make much sense at all. But when the string is not literal, no-one can guarantee the correctness of the string. I’ve seen you use #cull: in the implementation so at least there’s no error if the number of arguments is smaller than the collection. But what happens the other way around? Maybe you should call #valueWithArguments: and ensure that the arguments are filled up with nil. Other than that i hope such a construct doesn’t lure people to use tupel-like arrays. That just produces the hardest-to-understand code ever. Kind Regards Karsten — Georg Heeg eK Wallstraße 22 06366 Köthen Tel.: 03496/214328 FAX: 03496/214712 Amtsgericht Dortmund HRA 12812 Am 28.

From: Esug-list <esug-list-bounces@lists.esug.org<mailto:esug-list-bounces@lists.esug.org>> On Behalf Of Christian Haider Sent: zaterdag 28 maart 2020 13:43 To: vwnc@cs.uiuc.edu<mailto:vwnc@cs.uiuc.edu>; esug-list@lists.esug.org<mailto:esug-list@lists.esug.org>; amber-lang@googlegroups.com<mailto:amber-lang@googlegroups.com> Subject: [Esug-list] destructDo: Hi, I am using a nice little method #destructDo: for a while now and it feels good. In VisualWorks: SequenceableCollection>>destructDo: aBlock "Evaluate aBlock with the receiver's elements as parameters. aBlock takes its arguments from the receiver. 'ok' #(1 2 3) destructDo: [:a :b :c | a + b + c] #(1 2 3) destructDo: [:a :b | a + b] #(1 2 3) destructDo: [:a | a] #(1 2 3) destructDo: [42] 'not ok' #(1 2 3) destructDo: [:a :b :c :d | a + b + c + d] " ^aBlock cullWithArguments: self asArray In Amber: SequenceableCollection>>destructDo: aBlock ^aBlock valueWithPossibleArguments: self In Pharo and other dialects, I don’t know, but should be as easy. For example you can do (('2020-03-28' tokensBasedOn: $-) collect: #asNumber) destructDo: [:year :month :day | Date newDay: day monthNumber: month year: year] I like that the block is not the receiver (like with #valueWithArguments or #cullWithArguments), but the last argument. Now the questions: * I am sure that others came up with this. Anybody knows? * What are you using for this pattern? * I don’t really like the name, but haven’t found anything better yet. Maybe #destructedDo: or just #destructed: or: #withPartsDo:… maybe something shorter? Ideas? * What are you thinking about this?
