Hello Christian, " I don't really like the name," Maybe you could call it #tupleDo:? #(1 2 3) tupleDo: [:a :b :c | ...] Mark Mark Plas Software Engineer T +32 2 467 34 30 mark.plas@mediagenix.tv [cid:logomgxnew_3d44337b-2535-4d6a-9f5f-3fdd565513ca.png] <http://www.mediagenix.tv/en/cabsat2018/> Nieuwe Gentsesteenweg 21/1<https://www.google.com/maps/dir/?api=1&destination=50.872900,4.286429> 1702 Groot-Bijgaarden - Belgium<https://www.google.com/maps/dir/?api=1&destination=50.872900,4.286429> <https://nl.linkedin.com/company/mediagenix-ng><https://nl.linkedin.com/company/mediagenix-ng> [cid:linkedin_75b9c4f1-6a2b-497c-aab8-df56fe16b8e3.png] <https://nl.linkedin.com/company/mediagenix-ng> [cid:twitter_de4c3300-c6ab-4898-a962-b33ff662a322.png] <https://twitter.com/mediagenix_tv> <https://twitter.com/mediagenix_tv> <https://twitter.com/mediagenix_tv> <https://www.facebook.com/MEDIAGENIX/> [cid:Facebook-icon_6bef7545-f54e-4548-bfc4-1f07407f2642.png] <https://www.facebook.com/MEDIAGENIX/> www.mediagenix.tv<http://www.mediagenix.tv> Directions to MEDIAGENIX<http://www.mediagenix.tv/wp-content/uploads/2017/08/Directions.pdf> This e-mail and any files attached to it are confidential and intended only for the use of the individuals or entity to whom they are addressed.

From: Esug-list <esug-list-bounces@lists.esug.org> On Behalf Of Christian Haider Sent: zaterdag 28 maart 2020 13:43 To: vwnc@cs.uiuc.edu; esug-list@lists.esug.org; 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? Happy hacking, Christian
