Dear list, I was just wondering whether in class a = let x = Array.make 10000 0. in object val y = Array.copy x ... end x will be garbage collected or not. (this is just an example, I know creating x and copying is just doesn't make sense, but I wanted to point out that in my case, x doesn't need to be kept, but just used during object creation. I would like it to be garbage collected). I roughly recall a previous post where I think the reply was "intermediate values such as x are "kept" as members of the class", but I'm not sure. Thanks Guillaume.
