A rename func:
rename-ob: func [o name1 name2][context head change find third o to-set-word
name1 to-set-word name2]
>> o: context [a: 1 b: 2]
>> probe rename-ob o 'a 'c
make object! [
c: 1
b: 2
]
but there are many many situations in which it fails:
o: context [a: 1 b: [a: 3]]
o: context [a: 1 b: func [] [a: 3]]
rename-ob o 'a 'c
change the first a: but not the second one.
The same for delete:
delete-ob: func [o name][context head remove/part find third o to-set-word
name 2]
