Yes, that would be nice. Unfortunately a bit more involved than this 1-liner�

Hi.
I like tupleDo:

or matchDo:

and what about installing a full pattern matching, as in many languages e.g. Scheme : https://docs.racket-lang.org/reference/match.html

#(1 #(2 3 6 7) 4) matchDo: [:a (:b :@c) :d] | �]
here c would be #(3 6 7)

may be it already exist?
if not, would really be a +

Hello Christian,

" I don�t really like the name,"

Maybe you could call it #tupleDo:?

�� #(1 2 3) tupleDo: [:a :b :c | �]

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
