I look at implementation of BlockClosure>>ifError: . I did't know that it culls arguments to errorBlock.��

But what is this arguments? It is not error instance but specific properties from it.

BlockClosure>>ifError: errorHandlerBlock

^ self on: Error do: [:ex |
errorHandlerBlock cull: ex description cull: ex receiver]

Why people doing that?

Many users of it just pass given error like��

[...] ifError: [:msg :rcv | ...

��rcv error: msg].

Especially it is commonly used scenario by senders of ��#critical:ifError:. But it is different question.

��

I propose change ifError: to cull error instance.

What you think? Can be put it in Pharo 5? Such change can touch some packages
