Object copy

[David Bruant]

Hi Maxime,

Good to see you here :-)

This topic has been discussed recently on Twitter. See

I'm like Rick's answer in particular

as I believe a large share of cloning is just about data

As discussed in this Twitter thread, immutable data structures would be 
an interesting idea too. If an object is guaranteed to be deeply 
immutable, then, it can be passed around without the need for cloning. 
Clones are only necessary because the initial object is mutable in the 
first place.
Immutable data structures have been briefly discussed here recently:

(see replies too)
