Hi, you can use BlockClosure>>on:do:, like this:
[ #() atRandom ] on: Exception do: [ 1 ].
Personally, I would check the collection to be empty before calling.

Hi everyBody,
I know there is some kind of exceptions handling mechanism in Pharo but I cant
exactly remember where to find it.Actually, I would like to execute specific
code if atRandomis called on an empty Array or Collection.
I probably can still override errorEmptyCollection but maybe there is another
(less radical) way.And by the way, Would it be quicker to use exception
handling then just testing the Collection before calling atRandom.
Thanks
