I just discovered that there is no method like indexOf: aBlock where the index of the element matching the block is returned. What would be the usual way to achieve this functionality? Norbert

I knew it makes sense to ask. Only slightly embarrasing :) Norbert

Yep, because the closest I could create was using withIndexDo: and looking at #detectIndex:ifNone: confirms that. thanks, Norbert

We should do that more often. Especially here on the users list. IMHO it has three advantages: - asking here may show new ways of doing things. And we know in smalltalk it is most of the time the most obvious choice we do not find - I assume there are quite some readers in this list which have fun answering and trying things out if they do not know it. Sven is a good example for that. Iâm just an example :) - Everyone has the chance to learn something new my 2 cents, Norbert Am 12.02.2014 um 15:03 schrieb btc@openinworld.com:
