I think the name destructDo: comes from destructuring assignment. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/... <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/...> Norbert

Hello Christian,
" I don’t really like the name,"
Maybe you could call it #tupleDo:?
#(1 2 3) tupleDo: [:a :b :c | …]

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
