Hi Alexandre
yes it is possible, with the limitation pointed to by Stef: deep copy is
a complex thing and I don't measure the implications.
I can't figure out the result of a stack deep copy (ie a thiscontext
object), thinking just about this one, they are others.
May be DeepCopier would help ?
They are other situations leading to unpredictable results.
(Object>>#value)
ast link: (
MetaLink new
metaObject: true;
control: #after;
arguments: #( ) ;
selector: #value ) .
hangs the vm immediatly -it's like sawing off the branch on which we are
sitting.
This situation that can be protected with a simple fencing mechanism
(avoiding checking of some classes and/or methods), but more complex
cases will show off.
More investigations are needed here,
but even not perfect, this would still be a valuable tool IMHO
