The general idea, inspired from dotnet+smalltalk (I don't know if this fit well with smalltalk patterns, may be total junk and not doable ? -btw it's just a proposition) Collection>> asQueryable "=> a Queryable Object that would implement first, next, based on a predicate." ^Queryable on: self readStream. Queryable class >> on: aStream ^self new on: aStream Queryable>> where: aPredicateBlock self predicate: aPredicateBlock Queryable>> first self stream reset . ^self next. Queryable>>next [self stream atEnd not and: [ (self predicate value: (current := self stream next)))] whileFalse. ^ self stream atEnd ifTrue: [nil] ifFalse: [self current]. (...) col := #('a12' 'b12' 'a13' 'a14' 'c23' 'a16') asQueryable where: [:each | each first = $a]. col first. -> 'a12' col next. -> 'a13' Those dotnet linq patterns are cool, on a dynamic langage like smalltalk with tools like GTInspector + roassal and Moose, wouldn't it be ultra cool ? :) -- Regards, Alain

may be a first step would be to have findFirst: aBlock startingAt: based on findFirst: findFirst: aBlock "Return the index of my first element for which aBlock evaluates as true." | index | index := 0.

Collection with memory?

by stepharo

Hi I need a collection that does the following: col := #('a12' 'b12' 'a13' 'a14' 'c23' 'a16') asMyNewCollection. col findFirst: [:each | each first = $a] > a12 col findFirst: [:each | each first = $a] > a13 Do you know a collection that would work? So I have the impression that such behavoir could be defined with a kind of methods wrapper. Stef
