It is another perfect task for XStreams:

r := #('a12' 'b12' 'a13' 'a14' 'c23' 'a16') reading selecting: [:each | each first = $a].

r get > a12

r get > a13

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.
