Any object can be copied by transferring the value and the property list.
If we create an object 'A':
<lang PicoLisp>: (setq A (new '(+Cls1 +Cls2) 'attr1 123 'attr2 def 'attr3 (4 2 0) 'attr4 T))
-> $385603635
: (show A)
$385603635 (+Cls1 +Cls2)
attr4
attr3 (4 2 0)
attr2 def
attr1 123
-> $385603635</lang>
Then we can easily copy it to a new object 'B':
<lang PicoLisp>(putl (setq B (new (val A))) (getl A))</lang>
Inspecting 'B':
<lang PicoLisp>: (show B)
$385346595 (+Cls1 +Cls2)
attr1 123
attr2 def
attr3 (4 2 0)
attr4
-> $385346595</lang>
