It is nice convenient method for the case when you don't care what exact error happens. It is very useful for scripting. sum := 0. #(1 asd 4534 5423 sdfs) do: [:each | [sum := sum + each] ifError: []] Actually I never use argument version of block. But it definitely should be error instance and not of one of it properties.
