Hello,
I have an interesting question. My friend asked me the following
"(23:03:01) Ján Žiak: I think that the languages I have seen so far
there is no possibility to mark some part of code with a name and then
to use this code in some other code. I have stumbled on a situation
where I would need it --- I would like to call recursively some part of
method code without the need to put it in a separate method."
I wasn't able to help him right now, but for fun I have tried the following:
factorial := [:n | n <= 1
ifTrue: [1]
ifFalse: [n * (factorial value: n - 1)]
].
factorial value: 1
succeeds, but
factorial value: 2
ends with
`error: 'Attempt to evaluate a block that is already being evaluated.'
Is there a way how to make the above code to work?
